I would imagine that now since the JB has been in the wild for sometime regarding the PS3 and about 2 weeks the master encryption key was hacked by a crypto guy and we can now install any version firmware, custom firmware, homebrew software, and any OS. I would imagine it would be pretty easy to write a web controlled interface for the PS3 and then use Android to control it via a simple HTTP or HTTPS connection ? Maybe I am mistaken but I think it would be quite possible if not pretty easy for a good developer. I am thinking something similar to Tivo Remote. SOrry if I am repeating or mispeaking.
I may not agree with what you say but I will defend your right to say it with my life.
