The main features quake support requires are..
- loading textures from wad files.
- loading stuff from pak files
- loading/saving quake .map format
- loading quake mdl format

The code for all these exists in some form in 1.3.x, either leftover from qe4, 
added for halflife support, or added separately. Some of the code is unused and 
does not compile in 1.3. It should be simple to fix and reconnect things..
The thing we now lack is a "quake" option in the installers - this would prompt 
for the quake dir and install quake-specific files there, and create a q1.game 
with the correct editor configuration. We'll need the quake compile tools and a 
project file with correct bsp-commands, and no shaders.

best place to ask questions is irc.telefragged.com #qeradiant - you can save 
yourself a LOT of headaches that way =).
