How about surbl.surbl.org? Being the primary rbl, this kinda makes sense :)
Also on the other points about how to respond - I suggest the different IP per list as being smartest the octet based response is too non-specific.
Both ways are specific. The multiple A record response would give a separate address for each corresponding list. The bitmasked response has a distinct bit set in the returned address for each list. A 3 means bits 1 and 2 are set, corresponding to those the lists in the 1 and 2 positions. Its true that the bitmask approach gives only 1 query result, even for inclusion in multiple lists though.
This only leaves the question on how do we handle multiple listings :)
I assume you're referring to how the client handles the multiple or bitmasked responses.
