Hi Chad,
I work at UK and we did some evaluation / testing of a few. There are several variations out there - two of the bigger players being MobileIron and SAP/Sybase Afaria. They're similar in several ways and have a few key differences but we generally decided against it (for now) since most of our mobile users (students) aren't particularly keen on allowing us to 'control' their devices... even though it might be a nice service in some use cases.
If you're supporting just one mobile OS, you have a few more options based on what it is that you're trying to do. Apple's Profile Mgr might give you all the features you need if you're thinking iOS alone.
Be glad to share any specifics if you have Qs?
