One of the other ideas I proposed a while ago, but seems to have been ignored, is a BtVS / real people crossover in which Ozzy Osbourne discovers his long-lost nephew living in California and decides to make a surprise visit with wife, children, dogs and camera crew in tow. Needless to say it's the full moon. I really would like to see this, but I'm not the person to write it.
Back to work; I have to write a few paragraphs about RPG ideas involving the patent system and weird gadgeteering before I get to bed. Tomorrow's the one day Picocon SF convention at Imperial College so I probably won't get much done, but it's usually great fun so never mind.
