Math Input Panel Supporting Apps

I want a bit more functionality out of the MIP but I can find an app that supports it (other than Mathmatica which made the "Google killer", Wolfram (This is not a person but an actual company))

I know wordpad suports it but only as images, i know Office 2007 works with it but i have it installed on my other partition on XP and I cant find a portablised version that works on Win 7. I know an app that kind supports it but only shows the MathML source.

Any help!
