Not quite the same as what I was thinking.. I would like to see the
virtual hard disk show up on the gs/os desktop and be fully recognized
by prodos, etc.

I took a quick look at the IIgs firmware reference, and it appears
that it WOULD be possible to have some sort of emulation layer that
uses the UART to communicate with the host software...

The tricky part is actually *writing* data to Cx00->CxFF, so that the
'virtual driver' would look like a smartport device to the GS
firmware.

I am totally uncertain as to whether it is possible to even write to
Cx00, or if the memory mapped address space needs to be backed by some
RAM, or whether the lack of an actual card in that space will shadow
write to the GS RAM.
