Very impressive indeed :-), its still an entirely new game to bitbash a host though, compared to bitbashing a slave, which in its self is not something I would have even thought possible, until now.

How about a bit-bashed USB slave on the venerable 16F84? http://www.telefonica.net/web2/hidlcd/ Ok, so it had to be overclocked, and PIC isn't going to be capable of doing much else but it's a pretty impressive hack IMO.
