I'm not sure what the commercial vs non-commercial has to do with it,
since I've seen an awful lot of crappy commercial software - but I
suppose you could buy support for an ubuntu LTS release and then you'd
have your commercial software.

You mentioned regretfully moving to a different distro - which one? Is
it commercial?

Also, you mentioned that it works better for you in 10.04 alpha -
wouldn't that be worth trying? Since it will be an LTS release, one
would expect that to be well supported. It's certainly working well
enough for me...
