DNS permits multiple IPs per name.  However there is no standard for which one 
a 
client should use.  Typically, DNS servers will rotate the list on each access 
with some options to prefer the client's subnet if one of the interfaces is 
directly connected and clients use the first one, but different OS's and 
clients 
may use different approaches.  Web browsers generally try each address in the 
list until one works but other applications often fail if the first address 
does 
not accept the connection.

I guess I don't understand why you want addresses that won't work or work badly 
in your DNS at all.  If you have a dynamic dns scheme, shouldn't it give the 
best address for all applications instead of having to work around it in 
backuppc?

You can use ssh port-forwarding with any tcp app.  It's not backuppc specific. 
Someone has described how to do it on the mail list before - I'm not sure if it 
is on the wiki.  VPNs would work as well or better and are more general-purpose 
if you need things like windows management too.
