bazzer: As PSP as a remote could solve that for you, NGP is coming out "soon"...
Sorry mate but your acronyms have me stumped here. Is PSP the game console the kids play? The only games I play are on my iPod. Do you mean it's a remote for a PS3 or for an AV receiver? I don't have a clue what NGP is.
I already have a Logitech Harmony remote as well, but in this context the remote would have to be smart and do two way communication.
