Yes, that is exactly my roadmap.  I want maximum exposure, and not all 
PCs have USB, but all USB machines can buy a USB cable that provides a 
virtual serial port.  And, if I have to write a device driver, I'd 
rather write one for one of those cables, as it has more usefulness 
outside VIP.

Which is something that FDTI (your comments notwithstanding), and others 
have done.
