Random crazy question ...

Does anyone know of an IRdA dongle that connects via USB and that has MacOS/X drivers available?

I have some legacy kit that likes to talk infrared. And I've suddenly discovered that none of my newer Macs have IR ports any more, and an hour or two of google searching hasn't thrown anything to light. (Forget Omniremote -- it looks good at first, but it talks a different protocol, one used by remote control handsets, and can't do IRdA.)
