AdHoc Party is what you call the application which allows you to play online through the PS3. Right now it's Japan only, so you need a Japanese PSN account and 2G. I can find a guide for you if you're interested.
Remote play is controlling the PS3 through a PSP, connected by a local wired or wireless connection.
