[Coco] Using DriveWire to write network software

[Steve Strowbridge]

This was brought up in our CoCoCHAT! yesterday, if there was a way
internet-enable existing two player games on the CoCo, what a miracle that
would be!
I don't know all of the logistics, but I think the sharing of Joystick data
could be "streamed" with a custom i/o device that goes in-line to the
joystick port and gets the bits via the "internet" the 2nd challenge would
be actually sharing the screen, which Skype seems to do an OK job with.

I almost think like a custom version of an emulator may be the quickest way
to make this happen, with some modern protocol to share remote joystick
data and screens, but I'd love to live in a world where I could play CoCo
games with friends on-line (other than the already existing Global Thermal
Nuclear War)
