Both of these replies are quite unhelpful.  Could we stick to HOW to set 
this up and drop morality here.  Doesn't matter if he's at work or just 
at home and wants to double connect his connection.

I myself am curious to the answer of this one.  At home and work I have 
access to multiple connections.  And yes at work, I am open to explore 
them.  I'd like to see how to route http traffic to one connection, and 
leave the rest of the traffic onto the other.
