I’ve been trying to comment on Chucker’s blog (regarding JPEG-2000) for the last four days, and it just won’t let me. I give up…
Anyway, what I’ve been trying to say is that Second Life uses JPEG-2000 as its image storage medium in the backend. IIRC its because of both the streaming and image compression benefits (they use the kakadu libraries).
I’m not sure how it’s being done for their new FOSS client source, since I’ve not looked at it (though trying to create a Solaris/SPARC compile would be amusing – if the equipment were available).
