If you are interested in a C implementation of the BitTorrent protocol, see the libtorrent web page.
libtorrent aims to provide a robust, extensible C implementation of the BitTorrent transfer protocol. Focus will be upon providing tighter integration between the view/controller components of GUI applications and the underlying protocol model than are currently possible with the existing Python implementation. libtorrent is distributed under the BSD license.
I am working on a library that provides a C implementation of the BitTorrent protocol and the "bencoding" format (also used for tracker responses) is one of the most enigmatic things I've run into. It dictates not only one, but two underlying data structures necessary to store the data contained within the format (hash tables and lists) which makes writing generic accessor methods like those used in XML libraries nearly impossible.
I think it would've been much easier on developers if XML had been used instead of "bencoding". The largest and most code intensive portion of my C library so far is the bencoding processor (which is still only partially implemented).
Q: Does MOL run on the AmigaOne hardware (or in general, on non-Apple hardware)?
A: It does. MOL runs on any PowerPC hardware (except 601-based systems). However, the EULA of MacOS prohibits its usage on non-Apple hardware (it is of course perfectly legal to use MOL to boot a second Linux thoiugh).

A Truly Silent Desktop PC

The latest Dell Precision workstations run completely silent, except for the optical drives.
You can hear a faint whir from the fans if you place your ear next to the system, but otherwise they are completely silent.
Furthermore, they are extremely inexpensive. The latest deal on slickdeals.net was a $340 Pentium 4 2.53GHz system with 256MB PC2700 RAM, a 16X DVD-ROM or a 48X CD-RW, 30GB hard drive and 32MB Rage (in an AGP slot so it's upgradable) Slickdeals went so far as to say "You cannot build your own system for less then this."
I see no reason to spend more money on an underpowered EPIA silent system when a Dell can be had for significantly cheaper.
MPEG-7, formally named "Multimedia Content Description Interface", is a standard for describing the multimedia content data that supports some degree of interpretation of the information's meaning, which can be passed onto, or accessed by, a device or a computer code. MPEG-7 is not aimed at any one application in particular; rather, the elements that MPEG-7 standardizes support as broad a range of applications as possible.
It was assigned the number 7 under the assumption that MPEG-5 and MPEG-6 would be used for future video compression technologies.

Originally written on MIT-DM during 1977-1979, later distributed with BSD Unix (as a patched, sourceless RT-11 FORTRAN binary) The FORTRAN source was later rewritten for portability and released to Usenet under the name "Dungeon". Both FORTRAN "Dungeon" and translated C versions are available at many FTP sites.

When receiving a sigevent notifying the completion of an asynchronous operation, the sival pointer/integer union sent with the signal is not set, which indicates that all that was sent was a signal, and not a sigevent pushed onto a realtime signal queue.
The canonical behavior is to register a sival when making the original aio_* call to be passed with the sigevent that is sent when an asynchronous operation completes.
Without realtime signal queues, asychronous I/O is essentially relegated back to synchronous I/O, as you must poll operations for completeness. The asynchronous nature of the calls is lost without an asynchronous event notification system such as realtime signal queues.
I don't know how exactly you can claim to be using realtime signal queues on Linux for "ages" when they're obviously not present, at least on 2.4 kernels. What specifically are you using them for?
Linux is also missing kernel implementations of many POSIX 1003.2 features, including all asynchronous I/O functions and realtime signal queues.
SGI provided a patch to add support for asynchronous I/O using code borrowed largely from Irix, however without any means of notifying a process when an asynchronous request has been completed, asychronous I/O is entirely worthless.
There was a project to add support for realtime signal queues to Linux, but as far as I know it died before reaching completion.
Some other features would include a non-executable user stack. This is present and enabled per default on Solaris for all sparcv9 binaries, and a configurable option for 32-bit binaries as well.
"ESound? Asd? ARTs? It seems a little different in concept"
You should've read a little more about it. It's quite a bit more than a sound server, it's a graph-based media architecture, similar to DirectShow in Windows.
"FireWire 400 delivers data over cables of up to 4.5 meters in length. Using professional-grade glass optical fiber, FireWire 800 can burst data across 100 meter cables."
If fiber optics were used, how would the guitar's pickups and DSP be powered (not to mention the Firewire transciever)? A separate input for power? I don't think this is nearly as ideal a solution.
"Firewire currently tops out at 800Mb/second, and is a relatively new techology. Cat5e can handle 1 GB/sec, and has been around in its current incarnation for quite a few years."
Why is data transfer rate even an issue? Let's assume they use a 24-bit DSP with a 192kHz sampling rate (which is probably far superior to the DSP they'll be using in these guitars). Doing the math, that's:
192000 * 24 = 4608000 bits/sec
10bT would be suitable for those purposes.
"Also, the max length of a FireWire cable is 4.5 meters [firewiredirect.com], while Ethernet can do 100 meters [homenethelp.com]before needing a repeater."
Now this is a good point. However, why not use USB? USB has a maximum cable length of 80 feet. Furthermore, remember that the DSP and pickups on the guitar are going to need power, most likely using Power over Ethernet. If this is the case, the length restriction on Ethernet becomes more like 100 feet (depending on how much power is injected).
Furthermore, this will probably require nonstandard Ethernet frames (unless they intend to embed a TCP/IP stack into the guitar) thus making any use of this guitar with computers (which would probably be seen as one of the benefits of using Ethernet) only possible through custom software. Furthermore, Power over Ethernet is a nonstandard technology, whereas USB provides bus power to devices standard.
If the guitar were USB, you could plug it into any computer and it would work out of the box as a USB audio input source.
Given these considerations, I think it's ludicrous for them to use Ethernet over USB.
