[Users] choosing transport according to message size

[JF]

Also, we cannot use the t_relay() function with no params if we want
to force transport proto, we have to use
t_relay("[proto:]host[:port]"), and specify a host in the script. Am I
right? Is there another way to force the proto?

Thanks in advance.
