I think AMSAT-UK even has software available.

And with the addition of a bit of EEPROM, you could even pre-load the 
controller with ephemeris data for several satellites for several days 
in advance.  Emergency / field-day / portable operation without needing 
a computer.

Add a bluetooth module and an Android app, and you could have an all 
singing, all dancing, full-featured satellite station in a briefcase.

I'D buy one...
