Speaking of file sizes, xz[1] already provides better compression:

xz -k -9 linux-2.6.34-rc2.tar

     55320408 linux-2.6.34-rc2.tar.xz

xz -e -k -9 linux-2.6.34-rc2.tar

     54800808 linux-2.6.34-rc2.tar.xz

One drawback of xz is that it's not multi-threaded, much like bzip2 or 
gzip; would be great if it could be changed.
