1) One IP connection via a T-1. Second IP connection via GRE tunnel 
carried on first.

2) One IP connection via a T-1 that doesn't have transit, only peering 
with providers B and C. IP connections via two GRE tunnels to providers 
B and C.

3) One IP connection via MPLS over T-1. Second IP connection via 
different MPLS virtual circuit over the same T-1.

4) One IP connection via Frame Relay over T-1. Second IP connection via 
Frame Relay over the same T-1.

5) One IP connection via a T-1. Second IP connection via a different T-1 
that is multiplexed on the same DS3.

6) One IP connection via a T-1. Second IP connection via a different T-1 
that is on separate physical pairs, but in the same cable bundle.

you left out one connection via a chevy full of hollerith cards and the
second a canoe full of 7 track tape in waterproof containers.

we now return you to the real internet, where we invent new usefull
things occasionally but try to refrain from redefining well-understood
terms on a daily basis (unless we are in marketing).
