No, these parameters are not used for selection of socket, not even for 
routing. They are the values to be used to build Via headers, instead of 
using the values from sending socket.

mhomed helps also in selection of the right outgoing socket, when the 
route to destination is possible only from specific sockets.

Cheers,
Daniel
