Andrew,
I understand bridges and other similar interfaces do the same, but what
is the real reason for preventing a batman soft-interface from moving
between namespaces? I tried to figure this put myself, but I couldn't
find a real technical reason for that

(note - I am not a namespace expert as I am just learning now how they
work)

Cheers,
