Every peering agreement I've seen has language to the effect that an 
entity can't both be a transit customer and a peer.  Even if allowed, 
the temporary transit privileges would need to be provisioned and turned 
up which isn't going to happen instantaneously.

"We are a Tier 1 provider" tends to mean "I am a salesperson".
