Possible non-validation data that can be usefully propagated:

1) Block headers.

2) *Confirmed* transactions linked to an aformentioned blockheader.

3) Proof-of-work/sacrifice limited P2P messages, for instance to
co-ordinate trust-free-mixes or act as a communication channel for
micropayment channels.

4) With UTXO existance proof support propagate transactions
accompanied by proofs that all inputs exist. This would also allow for
implementation of Peter's low-bandwidth decentralized P2Pool proposal.

5) UTXO fraud proofs. (one day)


Strictly speaking #2 doesn't even need the protocol to be changed
actually as it can be handled entirely within the existing INV/getdata
mechanism. Sure someone could throw away a lot of hashing power and
get an invalid block propagated, but really so what? SPV nodes should
always take confirmations with a grain of salt anyway.
