I applied a patch I've had for awhile that adds support for SRV
records, and fixes API breakage for adns-1.2 and newer. This is now in
version 1.2.0, which requires at least adns-1.2.
I've also started adding some things to the wiki on the project home
page:
http://code.google.com/p/adns-python
Downloads are now directly available from that page as well.
