I'll take a) and c), but don't care so much for b).
About fragmenting, any tunnel ingress (VPNs included) can
do inner fragmentation today independently of all other
ingresses and with no changes necessary on the egress.
It's just that they need to take precautions to avoid
messing up the final destination's reassembly buffers.
