I found a bunch of academic work related to this topic under the  
keyword "multicast data origin authentication". Several of the  
proposed techniques use hash chaining.


It may also be worth using ECC instead of RSA/DSA to sign the Merkle  
tree roots for better performance.

I haven't heard of any P2P systems that use such techniques, so good
