Hi Daniel, very cool project! I am interested in hearing your thoughts on alternative image formats / compression methods.

WebP is very promising (also based on VP8) for lossless and lossy compression. Have you considered using it to compress PNGs in the same way Lepton is compressing JPGs? Odds are it wouldn't be bit-perfect though (despite being pixel-perfect).

Also interested in hearing about the tradeoffs between server-side decoding and client-side. Not to keep focusing on it, but WebP has native support in Chrome and javascript decoders for everything else.

I think it is a very exciting time for image formats with several promising new ones on the way (WebP, FLIF, maybe BPG but possible legal issues).
