[p2p-hackers] Multiple value per key query/response syntax?

[Kerry L. Bonin]

Hello!

I'm looking for any good discussions or examples of reasonably robust 
request/response formats for multiple transaction multimap queries in 
general, and multiple-value per key DHT in particular. 

I was considering using expiration timestamp windowing in the query as a 
sort of crude iterator filter for values that expire at a constant 
interval after storage or refresh, but I'm wondering about variable TTL 
vs. variable refresh intervals, vs. classic remote iterator design.

Any pointers would be greatly appreciated!
