 Maybe require the MMX instruction set?  MMX helps most for multimedia
stuff, but also for big memory copies.  SSE (aka KNI (on PIII and
P4), aka 3dNow professional (on AMD K7 Palomino and later, and K8, see
http://www.sandpile.org/impl/k7.htm)) is too high a requirement.  It is
great for FP math, esp. on P4 (with SSE2).  Requiring 3dNow doesn't make
sense, because that's AMD-only.

 Unix on Win32 is hard enough as it is, so yeah, good idea.  People with
older systems can use ordinary cygwin, or if they really want GNU/Linux,
install it natively :)

 Disk requirements are best specified in terms of free space
remaining/needed, not total size of disk.  (RAM and CPU use are scheduled,
so one process can use all of either while running, but disk space is not
like that.)  1GB of free space sounds sensible, if maybe a bit high for a
minimal setup.
