I'm looking into some way of making SDL output audio through libao. It's impossible to actually put the libao driving code into SDL, as the SDL is LGPL and libao is GPL.

What I've come up with is writing my own sound daemon that will link against libao and thus be GPL, but then writing an LGPL library which sends the data through a Unix socket to the daemon and having SDL use the LGPL library.

My question is, is this a violation of the letter or spirit of the GPL? Since Advogato doesn't allow comments to diaries, please reply through email.
