hello all , your project and forum are very cool and result is very good...at least you make quake3 still playable with linux....[ that is no longer to play doom3 or prey or quake-territory...may be because of the KMS..? ]
i make this post because i had the idea the developers should be able to invent an engine that can play the bsp maps of quake based game : Half-Life without too much headaches ;']
i made mods for HL years ago , the first one was using the dlls of opposing-force and maps from HL plus some from Blue-Shift or The Visitor mods to create a longer game with new models .
i uploaded mod Opposing Life2Life
here are the file : linux , low def and high def with the update for all
i made a second mod for playing svencoop 3.0 maps with the 4.7 dlls of the mod . herre is hhow i ppreseented it at steam forum :
Assault-Strike , The Cooperative Mod , is a bit heavy for an Half-Life Mod : 3 Giga ...
1.2 Giga for the 474 Maps
0.9 Giga for the 1439 models
to make it easy to have fun quickly , there are three mapcycles themed with mods [220 maps], maps [180 maps] and horror [60 maps] ...
i made two folders at Mega with files for windows and linux
the archives are the same and are made to make easier the install .
i also uploaded the live-linux server i used to create the mod .
i did not before because of the so many updates that break all...
but it is still working...so let 's share this masterpiece... [ should still be true , check was made 07-20-2015 ]
the iso is tailored for a 4 or 8 Go of ram pc and made to copy the whole file in ram , so server will never have to read from usb-hd or other hd .... that helps to have a stable servers
the file is around 1.69 Go and at mega

so i have no preference concerning the engine as rendering HL maps should be possible by all .
but hope a lot of what you can do
