I have heard a little of this (from TimeDoctor on irc) and I like the idea.
They even think - but on last place - to port some of the most famous game based on their engine, ours beloved SG is in the list!
You can find the project there on github: https://github.com/ioquake/launch and they even put a roadmap into the readme file
On my big surprise, even an article appeared in Phoronix. You can read it there http://www.phoronix.com/scan.php?page=n ... px=MTUzNzc
On Linux, just `git clone`, run `qmake` and then `make` and you'll have a lovely binary to test

TimeDoctor on #ioquake3@freenode.org isn't our friend TheDoctor for those who are susceptible to make a confusion.
