RISC OS on RISC OS

I’m now the proud owner of an ARMbook.
But sometimes I need more power.
For this, I use a Pi with VNC.

1/ I’m really waiting for the new VNC client/server to do this (as the old one crashes a lot).
2/ Is it possible to do a direct connection from one RISC OS computer to one another? It would be fun to just plug the Pi on the ARMbook to get access to it.
3/ If it’s possible, will the ARMbook support two USB Ethernet adapters? (one for Internet, one for the direct connection of the Pi)?

Of course, it will be simpler with an USB gadget mode support in RISC OS, with the emulation of an Ethernet card. So one could simply plug a Pi on another computer (PC, etc.) and use it directly.
