- merge net_udp6.c into net_udp.c
  http://www.viagenie.qc.ca/en/ipv6/quake2/ipv6-quake2.shtml
- kill off ctf/q_shared.c, it's identical to src/q_shared.c (Actually, work
  out redundant code and merge them... maybe some sort of libshared.a)
- clean up the #ifdefs that are throughout the code to be has-a
  tests instead of is-a. (using HAVE_* from configure instead of __blerg__)
- separate the video refreshers
- the video refresher loader code in src/vid_menu.c needs cleaning up, it's
  utter bollocks at the moment.  all the structs are very fragile, depending
  on specific ordering of each element.
- investigate the possibility of savegames not being tied to a particular build
- split out assembler per arch/os (we currently have gas i386 and win i386)
- make sure that we give back the mouse and keyboard if the game crashes
- dynamically get video resolutions from the X server (or SVGAlib or whatever)
  instead of hardcoding them... or do both
- have a look at http://bw-admin.sourceforge.net/ and
  http://www.planetquake.com/q2admin/ and see about merging in these tools.
- volumtric lighting?

- fs_sharepath and so on for user to set their own data install path
- mouse motion bugs in glx
- "teamspeak" headset... weel, mike support -- ogg speex encoding.
