That is pretty cool. I do have my spare rooted evo around that maybe I'll try this out just to show off how cool of a setup I can have. I didn't really like the GDMate app though (It bothered me to have to open the app to open the door) so I wrote a widget for it instead. smcgrath, If you want to check it out you can find it here
for a dollar. Let me know if you buy it and I'll refund the money.
