Ah, I really overlooked using the sockin_user interface for this task
and rather thought about implementing the virtual nic interface and
using the rumpkernel's TCP/IP stack - thanks for pointing out this
option. It is definitly a viable possibilty to check out.

Though that would certainly work as well, I think it is more reasonable
to implement it directly. 9p is a fairly simple protocol so using the
whole rumpkernel stack would be overkill IMHO :)
