	Right, but he's already explained that he is unable to connect to 
the same two providers in both cities, because one of them doesn't 
have a presence in both cities.

	That doesn't help if that one provider goes Tango-Uniform.

	Can we gain redundancy by connecting to a different provider in 
each city, but still find a way to be responsible?

	As said above, this isn't possible.  I'd like to learn what could 
be done in this kind of situation that would allow the desired 
redundancy, while also being responsible.

	I'm not a manager of a large network (where I might have this 
kind of problem myself), nor am I employed at a large ISP (where my 
customers might have this kind of problem).  But I would like to 
learn.
