I would hardly say copper ethernet is nearing an end. It can easily sustain gig speeds, and specs are in the work for 10gig. If anything, this severely limits the ability to connect to the network.
Why not wire every room with Cat6 and allow people to connect and whatever speed their computer allows. Even if you get a gig-ready computer, you still have to shell out an extra couple hundred to get it to work.
This seems to have been nicely accomplished already. I can't access any part of the site except that which was cached in the first couple clicks of browsing.
I've never had a problem with it before. Maybe back in the day I authorized all my computers, but I don't remember doing that. I'll have to check and see.
But if worse comes to worse, you can always burn and rip to mp3. I've never had problems with that in the past.
How many computers do you have? You can authorize the files to be played on up to three computers, and if you have more than that, just set up a iTunes server. I have one box that has iTunes which I buy the music from. Then I just leave iTunes running all the time and I can then access the music from any computer in my house.
(you can also just burn the song to CD and rip it back as mp3...)
I'm actually a little surprised at the small amount of network tools that have been suggested. While Ethereal is a god send (it recently solved a very puzzling DHCP issue that we were having on one of our networks), it isn't the end of what you need to have.
Buy one linux server, and then discover the wonders that are ping and SNMP. Simple tools such as Nagios and MRTG (or NRG or Cricket) can do wonders for helping spot problem switches/routers and congestion spots.
For example, every device we have is pinged 3 times every minute, and queried for bandwidth usage every 5 minutes. This has helped in finding bottlenecks, and the occasional switch that reboots every few minutes. (MRTG alone convinced the higher ups to buy new gear for our Datacenter and give it a dedicated link to the Core).
Also, setting up a wonderful SNMP trap server can be very useful. It allowed us to find a switch that likes to reboot at random intervals (the switch is 5 years old and being replaced this weekend). Of course, having it send a trap whenever a switch reboots is just the start of what certain switches/routers can do.
Also the use of Snort to sniff traffic that can be potentially malicious can be very helpful in tuning firewalls and finding those script kiddies. (use ACID for a pretty front end)
Another nice tool is NTOP Does almost everything NetFlow does and has a pretty graphical frontend built in. (I recently used this to find out that one of our firewalls was sending gigs of syslog data to the wrong server.)
And with the mention of syslog, might as well throw out a link for syslog-ng. yet another useful tool.
Basically the point of this is to say that sometimes it's best to let your equipment do that talking. They'll usually tell you what's wrong, just as long as you've set them up to do so. I found that once we put a lot of these tools into full production, we were able to cut down on our need to sniff the line whenever problems came up. This isn't to say that Ethereal isn't needed. That's hardly the case. Its use is still huge and shown all the time.

Most new laptops have an option for gig ethernet on board. We just got a few new Dells in at work and they all have gig ethernet built in.

Boastology works good for me. It's got comments, voting, a nice pretty calender, and other stuff.
