Monitoring Jobs Across Servers/versions

Hi all,
I've been digging around the last few days, looking for the best way to monitor all the jobs on all my prod servers. Using EM or SSMS is BS. I've been thinking that perhaps the best strategy is to write or modify a script that gathers information from sysjobs and sysjobhistory on all servers and then inserts it into my main DBA database on my "admin" server. Of course this script would have to be on all servers and be in a scheduled job itself. I'm thinking that I should probably categorize every job in the company and break out my reports that way too. I'll probably throw all the data into a cube so I can do some at a glance checks to see that everything is running ok. I'd like to trend run times with the data too.

Anyway as with most fun projects there are many different way to accomplish this. I've hit on one above and I've seen several others. What are some of the solutions you guys have come up with, what have you tried that didn't work so well and what are some pitfalls that I should avoid in setting this up?
