There are those little things that HP sells (NetEye?) that are approximately
$200 US and do IrLAN.  Uh, well, there _used_ to be something like that ...
maybe they don't sell it anymore.

Ah, wait, I'm wrong (it was "JetEye", and it wasn't made by HP):

However ... I saw some pages that imply that Windows 2000 ditched IrLAN
and IrCOMM for something they created called IrNET (which there isn't
a standard for).  And I'm not completely sure this box isn't PPP over
IrCOMM (but I really do remember that the JetEye was IrLAN).
