Excellent! I just found this post yesterday, and installed the app from the marketplace last night; on an EVO running Android 2.2.
It asked for the 6 digit "key" and also my authorization name and password, I entered them and it all worked great.
However, as previously mentioned, it's a work in progress.
There is still a bit of functionality that needs to be added to make it a true remote replacement.
The first thing I missed is a BACK button. I clicked on the wrong video, and it took me about 10 minutes to figure out how to navigate to a location that would let me get back to the menu to pick the correct video.
Obviously, some direct function buttons would be good also, like rating, delete file, Media Type and some others.
if it looked a bit more like a "regular" remote control, and used more of that type of "standard" feature set, I think you've got a winner.
I've never bothered to program my remote to work with MC, and instead just use a mouse, and (occasionally) a keyboard to navigate to do what I want.
Having this be a true replacement for a "standard" remote control would be a HUGE step forward in my eyes.
I hope to see this project progress toward these goals soon
