Switched helps. ftp can compress files, so you might be getting some "fake" results there, unless every one of those files was already compressed (e.g. mp3s). I discovered this when I ftp'd a 1 MB file at 32 KB/sec on my 28.8 modem! The maximum my modem does is a little over 3 KB/sec.
I do network programming, and the applications I develop require me to do a lot of file copying. Copying large numbers of files (over 1GB, this is a mixture of lots of small files and some very large files) in Win2K I realistically get about 3-4 MB/s. When a Win98 machine is involved, its around 50 - 75% of that speed. This is on a switched LAN too. I haven't done proper tests involving SMB on Linux, so I don't have numbers on that.

I seem to recall that there is already a technology designed with this purpose in mind.. what was it.. oh yes, now I remember.. "encryption".
The case of ringtones is slightly different to any other case of fair use or copyright violation in another way. With other "music" violations, the purpose of the violation is to listen to the music. With ringtones, the purpose is *NOT* to listen to the music, but to STOP the playing of the music as quickly as you can (by answering the phone). I don't have a clue what that means legally though, but I suspect it may mean something. IANAL though. Would like to hear what a real IP lawyer has to say about it.
I think its quite clever.. he gets modded up, then when mods are frozen, he changes his sig, and a stupid meaningless FP is modded up for eternity:) I'm actually somewhat impressed that this guy managed to change his sig to a link to something meaningful related to XML and post a FP in the short time available before anyone else got to FP.
"Is it a violation of fair use if I hum a few bars of a song?"
Not yet, but don't worry, the RIAA is working on it.

In theory, yes (i.e. if you could stream data straight off the HD and out onto the wire). In practice, no. The data must first be read by an OS, is seldom contiguous, has additional FS overhead to be read, there are additional delays in network protocols (e.g. in the protocol layering (SMB/TCP/IP/802.3, also for a reliable protocol like TCP, every byte that gets sent must be acknowledged), in processing interrupts, the computer must also process other things (GUI, mouse etc, and perform scheduling). Also, multiply all the overhead by 2, because the other computer needs to be *reading* that data, and usually also saving it to a hard disk. Add to that network collisions - on an 802.3 100 MB LAN, the high number of collisions that start to occur as the LAN approaches > 70% usage starts to seriously degrade the network (there will be collisions even with only 2 PCs on the LAN copying between each other, because remember, you have addition protocol overhead for ACKs etc).
So in practice it is nearly impossible to copy files from one PC to another over a LAN at anywhere near 10 MB/s. If you manage between 3 and 5 MB/s, then you are doing quite well. If you don't mind unreliable and you are streaming the data in one direction (e.g. with UDP), then you may be able to do a bit better than that, but in my experience I've found that it is *very difficult* for one computer to even approach saturation of 100 MB, even with data unicast with UDP that isn't being read off a hard disk. You can try this yourself, write a simple UDP sockets app that just sends data on one end, and receives data on another, then output some stats on the number of bytes sent/received.
See Tanenbaums "Computer Networks" (3rd Ed), he has a useful section on the performance of networks, basically discussing why most of the latency is in software, in the protocols etc.
Oh please. Flag burning is just another completely impotent form of protesting. Of course they don't care if you can burn flags, it means nothing. Environmental movement? I think America's actions speak for themselves. The worlds biggest producer of greenhouse gasses pulls out of kyoto because "it would be bad for our fragile economy", not to mention the attitude of the people, big gas-guzzling SUVs are the order of the day, a country where anyone who is vocally pro-environment is taunted and labelled a "tree hugging hippie" who "threatens the american way of life" (i.e. excessive consumerism, complete and utter devastation of resources. We're talking about a country where they ban movies/books like "Lolita" and "Catcher in the Rye", not to mention McCarthy era politics, a country that sends its own troops to fry in nuclear bomb tests ("but wait these things were all in the past, that sort of stuff doesn't happen anymore", yeah right whatever), a country that gives its authorities excessive surveillance powers (ala Carnivore), a country where any organization with enough money can buy laws. Even after nearly fifty years, the influence of McCarthy propaganda on the American public is still painfully obvious, even when reading slashdot.
I wouldn't expect you to see it anyway. You're far too wrapped up in US propaganda to have an objective viewpoint. Its really too bad - Americans simply cannot take any criticism whatsoever - they immediately go on the defensive - its impossible to get any point through, no matter how much merit it may have. Its so sad to see so many otherwise intelligent people just soak up all the anti-China sentiment in the press, without any attempt to analyze it for what it might actually be. Watching CNN interviews recently, when those US spies came back, its so sickenly obvious actually.. "So, has this experience given you a deeper appreciation of what it means to be *American*?".. "Yes, it really has reinforced my feelings about how great it is to be an *American*, and how great a country this truly is, and blah blah *America* blah blah *America* blah blah." I mean, if this were *subtle* propaganda, I could understand it, but really, its so incredibly in-your-face, it boggles my mind that Americans don't seem to see it for what it is.
"See, in the US, when you don't agree with a policy, you can yell at your Congresscritters, hire yourself some lawyers (or talk with the ACLU), march around outside with a sign telling politicians where to stick it"
All of which appears to be about as effective as banging your head against a brick wall, as far as I can tell. I can't say I can think of a single example of any of the above resulting in any change of policy in the USA, ever. The authorities continue to do as they please, systems like Carnivore remain firmly in place.
In China, the government doesn't pretend that its people don't have a voice. In the USA, the people are led to believe that they have a voice, but in actual fact nothing they ever do or say influences government policy in any way.
So basically in China you have absolutely no power to do anything about the things you disagree with. But in the states, you have.. uhm.. absolutely no power to do anything about the things you disagree with. Enjoy!
