I had thought about buying this machine. It would have been a
further incentive if I could have plugged a wireless interface between
it and my computer.

There are lot's of serial modems, etc, which can be inserted in-line
into RS232 links. First, you need access to the serial llink.

You could start here (the "official" roomba hacker info page):

Excellent. That page has a link to SCI spec in pdf form. Regular
TTL-level RS232 at up to 115200. Good intel on roombavac sensors.

hmmm.... Someone should add speech to a roomba.
