Just as a quick digression...

xz has only marginal improvements in compressed size over bzip2, and takes 
a lot more cpu/memory resources to compress.  In most cases, I'd say it's 
the wrong choice for a compression format.

However, the one place where it is unequivocally the *best* choice is one 
that will make it well known: Distributing archives.  It does beat bzip2 by 
a small amount, and it's *decompression* time is *much* faster than bzip2 - 
on par with gzip.  Plus decompression can be done in a fixed amount of RAM, 
regardless of the size of the files being uncompressed.  For files that are 
compressed once and then decompressed many times on many different boxes - 
like a FreeBSD release - it's a definite win.

But for files that will be compressed and uncompressed regularly, or 
compressed and usually never touched again, it's worth thinking about 
what's the best balance of resources.
