what I wanted to know was if anyone knows of a BL or URI BL that returns or plans on returning something other than a loopback address as a positive response to a lookup?
None I'm aware of, but you said 127.0.0.0 to 127.0.0.255. It's in fact the complete 127/8 range 127.0.0.0 to 127.255.255.255.
There is a draft to get this on "standards track", finally, see http://tools.ietf.org/html/draft-irtf-asrg-dnsbl
