Comment (by sqrt2):

 I've been looking through the code, and (considering that I can use my
 alternate bridge addresses as Bridge and that works flawlessly) my
 impression is that as an OR, reachability self-testing is the main area
 that currently depends on addr/or_port being simple uints.

 It is also my impression, considering that IPv6 self-testing is currently
 not being done at all, that this ticket could be addressed with another
 hack. We coul add another field for additional IPv4 addresses/ports to
 routerinfo_t, and modify router_dump_router_to_string() and
 router_parse_entry_from_string() appropriately. In other words, we would
 be ignoring reachability testing for the additional ORPorts completely.

 (One could do the same for additional IPv6 addresses, but because blocking
 entire netranges is much more dangerous for IPv4 than it is for IPv6,
 additional IPv4 bridge addresses are probably a lot more useful to the Tor
 network than is the case for IPv6 addresses.)

 Am I missing something or would that work, and should we do it?
