[racket] iRobot Roomba robot hacking in Racket?

FYI, I'm almost finished with (untested) code for a Racket Roomba 
library, and plan to test and release it once my iRobot serial cable 
arrives.  It should work with all Roombas (and iRobot Creates) of the 
last 6-7 years.

Initially, I plan to control the Roomba using a serial cable tether to 
an offboard laptop.  Later, if I have time, I plan to have a Raspberry 
Pi onboard the Roomba, which can switch between running stored Racket 
programs onboard and being a WiFi-based bridge for controlling Roomba 
wirelessly from an offboard PC.  (This would permit using DrRacket to 
develop/debug the program while still controlling the robot, and then 
running the same program on the robot without the offboard PC.)

If anyone has any interest/need for this, let me know, and we can 
compare notes.
