Actually it seems that this is yet another case of trying to get mod_python to hook into more places in the Apache framework; specifically to hook into other modules.
We've already been discussing specific-module hooks for mod_ssl - http://issues.apache.org/jira/browse/MODPYTHON-94 mod_include - http://issues.apache.org/jira/browse/MODPYTHON-104 In fact there's a bit of potentially useful discussion in the notes for those JIRA issues which is valid for any module-hooking in general (along with this mailing list archives). I'd say it might be worthwhile to at least create a new feature-request issue for mod_dav hooks though; just so it's on the record. BTW, even though it's not what you asked, it should be possible to totally implement DAV using only the features already present in mod_python (without mod_dav); but of course you're doing a lot of the work yourself (but on the other hand you get to use Python rather than C). -- Deron Meranda
