You probably have support contracts with vendors for software and hardware already? Linux is no different.
Anyone in a corporate environment that isn't a GOD on that particular Application/OS/Hardware should have a suport contract. User groups are great for the home user, but in the corporate world you need an answer NOW, not in three days. Linux support is out there.
Is that sweet enough?

I guess I sometimes come across as a chinese dish. Sweet and sour pork? :^O
Peace all.
