Yessss ! FLAC it is.. the near future. (there are some more lossless ones like APE)
The lossy compression like MP3 was developed in a time with low speed and bandwidth, to get a decent Inet-traffic.
These circumstances have been drastically improved, so MP3 or OGG will appear to have been a temporary solution soon.
So, if a new format should be implemented, I think it's better to look ahead for one, than to look back.
A FLAC makes a WAV about 50% of the filesize, which is still quite substantial.
Most of my tracks are published in the OGG format now, free to download. Because I don't consider it the original.
I compare it with a printed poster of an original painting.
I'm planning, as an experiment, to publish (maybe only on demand) a 'quality' version of a track in FLAC format.
So one gets the original WAV back, with the possibility to burn it on an audio-CD.
I would publish the FLAC in a 7-zip file. Not to make it smaller (remains the same), but than I can add things like cover-art.
