The only problem I faced was a software stack problem. We had put an IrDA in a Mp3 player and we only implemented the Ir because there was no open stack for iRDa. This was 1998, so many years ago.

you won't hit a patent problem that I know of.

Jus like the openmoko met the MPEG patent ?
If it is a patent problem, nothing we can do.
But if it is only the stack proble, there is an open source IrDA stack now.
I google and get it.
And we maybe write it into a FPGA to ack as a hard stack.
