Except that you have to manually bump the version in those packages if yum
should automatically pick up the new version (just realized that tonights 
rebuild of qemu was useless, since the version is the same :-(, sigh).

I think a compat package would make the coupling between server and client 
looser, (i.e. one could run old clients on the same machine as a new server).

Due to limited time and dependency on qemu on some of my testing machines, I 
still have not been able to test 3.6.0beta3. A -compat package would have helped
me a lot (but maybe given you more bugs to fix :-)).

Sorry that i missed the meeting (due to DST change and not doing
date -d "12:00 UTC" [should be in the etherpad])
