I need to bitchslap Daniel until he finishes his vague ArcEm podule
support such that there's a nice way of getting data into RISC OS
without having it poll.  Once he does that, writing a DCI driver to make
use of a TUN/TAP devices on the host side shouldn't be tricky (I have
some proof of concept code based on the EtherY sources.)

I don't see why NetSurf shouldn't work, either.

I had a disgusting thought about that the other day: Emulate a load of
podules that just have memory in their mapped space.  Then trap Dynamic
Area SWIs to use the new memory.
