Tested this with my test-client.pl script here, and as you said, doing PUTs with a proper header does lead to CGI.pm parsing out PUTPARAM. (As a sidenote, what will CGI.pm parse out on other methods like PROPFIND? PROPFINDDATA??)

Problem is, if you intend to use this all here for WebDAV, you can't control the clients behaving nicely. For example, gvfs, GNOME's DAV client - as I see it - does not set any headers on requests...
