Those are a lot of interesting links. They are all pretty expensive, 
though. A bargain basement option would be an AVR butterfly. The Atmel 
micros have UART/SPI/I2C built in, and the butterfly is 20USD. You could 
even probably achieve USB with this, there is software bitbang (!) USB 
available for AVR.

That one is a little bit out there. That board is probably $10K, and you 
need a $100K Tek Logic Analyzer to use it. :)
