This would kill battery life, haven't you ever used remoteplay before. You get ~<3 hrs on a slim battery while playing PSP UMD-based games online.
How about PS2 remoteplay capabilities, or expand PS3 remoteplay and add "dropped" features like the ability to use the PSP as a rear view mirror in Formula 1 (shown off years ago at E3).
