We have something that might work. The COMMANDIR is a (soon-to-be
commercial) USB transceiver that we built with Linux PVR software, like
MythTV, in mind.
Here is the brief feature summary:
* Transmit & receive timing is all hardware based (accurate/reliable)
* Supports 4 independent 'eye' transmitters (so 4 identical devices,
like sat boxes, can be controlled separately)
* Up to 4 can be daisy-chained (for 16 independent transmitters)
* USB 2 compatible, USB powered
* Fully LIRC compatible (we maintain the lirc_cmdir driver in CVS)
* (separate from LIRC, it also supports an LCD display with LCDproc
and the like)
To respect the list etiquette, I'll drop you a line off-list
regarding commercial details.
