did not experiment extensively with this, but i had mixed success --
somehow some problem seems to exist. Plus i am not sure on the
visibility in the outside of data generated with the aliased IP.

prova# ifconfig tun0
tun0: flags=8051<UP,POINTOPOINT,RUNNING,MULTICAST> mtu 1500
but still i have no idea what ppp does with this. Plus, there is the same
problem with addresses.

i don't know enough about mrouted internals. I will have to ask Bill Fenner
about the way it works.
