Isn’t it ironic that there is more attention paid to iphone remote applications for windows media center control rather than WinMo apps or AppleTV control? I have been comparing the different applications and I have tried a few of them. I drew up a comparison table for my own sake that might be useful to others.
My main control is a logitech 890 remote with RF control of the PC. This works fine for most uses. I also have the gyro remote connected when I really want to use the mouse and open and close windows. Both work reasonable well across walls from about the same distance (a few feet less than ideal but I I use the hand closer to the far closet and they work 
). I find an iphone less than ideal remote for regular use since I do have to wake it up, unlock and find the app, wait for app to reconnect and then control the pc which takes too long.
However, what I have been looking for is an app to use with the TV off so I select and start music streaming to the receiver without needing to switch the tv on and off. The Library column in the table below is the one that indicates if the app supports display of the music library on the phone to browse.
I had bought PlugPlayer for PopcornHour a while ago and it works well with WMP Sharing to browse the library and play music without needing to switch on my TV or projector. However, it is finicky about picking my receiver to play to whereas it was much better at playing to the PCH as a media renderer. vmcMote is the other solution that I have found works for non-TV music playing. I bought the vmcMote full version which I am trying out. I do not want to buy all of them to try and pick one so if someone has significantly better experience with one of them then let me know.
I will try to update the page as I experiment more and/or find more applications.
