It would be nice if GUI's can be distributed as plugins...

Isn't XML often used to describe interfaces?  Perhaps we can use a
structured form of storing data like XML...  But that is just a random
thought. :-)

It's not easy on the PC.  But AFAIK it should be easy with EFI and
IEEE 1275, but I have not taken a close look yet.

Right.

Right, but it would be the best if we think now and design the
interfaces.  We don't need to implement it all and it does not have to
be perfect, it is important to have a good foundation we can build on.

Agreed.
