Yes, there is: t_relay_to_udp. t_relay_to_tcp, t_relay_udp, t_relay_tcp,
t_replicate_udp, t_replicate_tcp. For stateless forwarding: forward_tcp,
 forward_udp. Note however that stateless tcp to udp forwarding is not
 recommended (you won't have any udp retransmissions => loss of
 reliability).

You should also always record route (ser should always be in the path to
"forward" between the different protocols).

BTW: all the stuff above is supported only by the latest release
(0.8.11).

Yes, ser will try to keep the same transport by default (unless
 a special *_{tcp,udp} script function is used, or the transport is
 specified in the uri).
