i stumbled upon this on SDA: http://speeddemosarchive.com/forum/index.php/topic,11041.msg280704/boardseen.html

Baker5 wants to make a minimal flash quake demo player based on: http://www.silvergames.com/game/quake-flash/

would be nice if someone would make a site similar to that (and resembling QuakeLive.com), with a minimal OpenGL client embedded with a couple of custom maps (ztn, aero - since dm maps are not fully GPL'd yet). would be a great starting point for playing QW.. and with online stored configs you could play anywhere if you don't feel like carrying your home setup.
