I have an applet for my $10 web cam that has lots of wierd FXs but no CK :(

Datavideo do a hardware keyer for less than a king's ransom:

I've watched it do its thing in the flesh and it seems to work quite well. Cheap camera into it and the output into an A/D converter and you're set to go really. Sorry it'll cost money, more than some plugin running behind a web cam but I think the quality difference will be pretty dramatic. The nly live plugin I can find is a SDK from MediaLooks.

Thinking outside the square it might be easier to just rear project the background. A cheap video projector and you're done.
