That was one of the things I double checked. The packages that had 
Multi-Arch: Allowed in the Ubuntu repo Packages files still had it in our rebuilt and
manually generated local channel "copies" as well. Whatever is happening to cause those
packages to be removed, I don't think it's got anything to do with Multi-Arch. 
However the python2.7 package upgrades being the trigger for that removal raised
my suspicions and I tried to eliminate that possibility first.

Cool. We had e-mailed about what would be needed to retrofit that functionality into
Spacewalk db and code properly quite a few months back but I haven't had time to work on it.
