Instead of a TCP channel (which means software), what about using DNS? 
If the SA clients did RBL lookups that contained the details as part of 
the query, then if your end parses DNS logs (I'm thinking djbdns, don't 
know about BIND), then you could extract the data yourself.

You could even introduce a token into the RBL to stop the bad guys 
corrupting your corpus (a problem you'll have to deal with anyway 
whatever the network mechanism).

e.g. (token == "834ufg754")

ie only the dns logs that contain valid tokens are legitimate
