I guess we're in a bit of a waiting game then. Too much stuff is tied to RHEL to easily switch for us, but TBH we're starting to see more people wanting Ubuntu (ugg) / debian because ML seems to be there. Also most commercial software I've seen tends to offer .deb and .rpm or just .deb actually so more and more it's RHEL that isn't packaged for - and that's been for years now.
