Lougher has made a pull request for xz support (effectively lzma2) for squashfs for 2.6.38. The merge window closes in about 3 days, so we should know pretty shortly whether or not this request is accepted, but the odds look good.
We already have squashfs-tools support ready to go. I'll work on adding a documentation patch to note xz as an available compression type soon. Once we have a 2.6.38 kernel in rawhide (assuming the patch set gets pulled) I like to switch the default to using xz instead of gzip for livecd-creator. If we find problems we can switch back easily, but I'd like to get testing going earlier rather than later.

Linus has pulled this patch, so unless something really unusual happens we should have xz support for live spins for F15.
