We've been discussing these things.  Something like this can certainly be
done, but it's not entirely clear exactly how.  (One problem is that IrDA
attachments are very transient; they can come and go easily.  Should the
device persist or not?)

For now the idea is to have it all in userland and allocate a pty for IrComm
devices.  As things progress we can migrate things into the kernel.
