I have though about this thing as well recently.
And looking forward to anyone's answer
The thing that bothers me, is how openswan then should know that for 
instance, the main network link is down and it should use the second ip.
I mean, let's assume situation that we have 2 WAN connections and one of 
them get's down. And I'd like openswan to switch the tunnel to the 
backup one and then to restore it when it's back again.
However I'm still not sure if is not supposed to be a function of the 
routing itself.
