Good quality of course, but i'd much prefer higher framerate over huge resolution.
~1,7mb / second, you'd hit a Gb for a 10 minute movie.
Can't really say anything about the content, except for the music, really the techno equivalent of a php-nuke website, push the "make techno" button on your "music maker 2002" and this comes out, "hello template".
These specs on a Dimension 4400 doesn't mention any AGP slot, however, this specification of the chipset suggest it supports AGP4x. So if you do actually have AGP since the chipset should support it, it's still only running in 4x, whereas a modern AGP card would want to run in 8x.
In my opinion, you've waited too long for a performance upgrade, too many core things about your PC are outdated (400mhz FSB, AGP4x). Still, if you have AGP you could buy a decent graphics card which you could bring along for a completely new PC.
If you'd download everest, click "Report", do a "System Summary only", "Plain text", when it's finished hit "Save to file", save and attach the file to a post here, giving advice would be simpler (knowing what you have and what you don't).
spsamsp, PCI-E is still so new you can buy a brand new computer without it, a PC from several years ago will not have PCI-E, PCI-E and PCI are two extremely different things.
LFS (demo) could supply the master server with one of these hardware-based keys, if the key doesn't exist an 'account' is created needing no user input, the player gets assigned a username tied to this 'account' (guest19538 etc.), which server admins can properly ban.
