No, the only guaranteed to work configuration is when all frontends and 
backends are running the same *protocol* version.

Again, as long as the protocol is the same, distribution does not 
matter. I have 2 Debian/KnoppMyth machines, and one CentOS machine, they 
all happily talk to each other, because they all run the same protocol 
version. It just happens that I run current SVN trunk on all of them.
