Hi Anne,

It's not O(N^2) as long as you're only integrating insurance systems
with one another using the same WSDL.  As soon as you step outside of
insurance, such as if you wanted to integrate banking, CRM, etc.. it's
O(N^2) because each new system added (that doesn't have an interface
that you've already integrated to), requires new integration work.

If you don't buy that argument, would you agree that having less
interfaces means easier integration?  i.e. that it's easier if all the
insurance companies agree on a standard interface than it would be if
they didn't?  If so, would you also agree that if banking and CRM
companies could agree to wrap themselves in the same interface, that
this would further reduce integration costs?  And if yes to that, then
wouldn't the ultimate interface be one that could wrap all systems?
