FLAC is basically a compressed WAV (advanced compression), so high 
quality sound but low compression ratio, also it is not resilient to 
dropouts, it was not designed for streaming.

If you can not find a suitable codec for your application just use a 
streaming one like mp3, is not the best for the task, but can do it, 
FLAC can not.

Maybe you may think in Opus http://opus-codec.org/ as it is open, 
royalty free (mp3 is not free, you must pay royalties for the encoder 
side) and source code is C89 so it must be compilable (libopus) in 
almost any platform without a titanic effort.

Of course a RTP or alike transport is desirable, but it will introduce 
much more complex tasks.

I think that if you like to continue this discussion we should move it 
to fpc-other.
