Now that we have WAV support, I was wondering if there was any thought to implementing some lossless codecs, such as FLAC, LPAC, Monkey's Audio, etc.

Some thought, yes, but not much more than that. I've looked at FLAC - the reference decoder is in integer-only C, so it should be fairly easy (for empeg) to integrate it with the player. The lack of plugin support in the player makes this hard as a third-party project but is in theory possible with on-the-fly translation to WAV.
