>Comments?  Thoughts?

I had looked at this for a while some time ago.  It really seemed to me
that the "right" thing to do was to put things like IrLAP and IrLMP
into the kernel (since those are the "per interface" things) and have
userland programs create a PF_IRDA_LMP socket (or whatever you wanted
to call it).  But since I never did anything, your approach sounds fine
:-) At least that would get us to start playing with some IrDA code ...
maybe the next level would be to bring it into the kernel.  Might be
tricky to do IrLAN without kernel support (but I guess you could use
the tunnel device).

BTW, what's IrMUX?
