I quickly tested HTTP::DAV via dave and a quick glance at the code, it did everything just fine; if your installation of LWP is "ssl-capable", HTTP:DAV is either. First impression: solid, very good; claims to work with apache2, that'd be a real asset.

It's build on top of solid modules (namly LWP, URI, XML::DOM and a couple of codecore-modules) and the code looks clean and indeed mature.

From this half-hour tests I did (well, actually 45min ;-), I'd recommend this module: Use HTTP::DAV (if you're not trying to navigate fully populated 747s with a weird dav-based approach, maybe you should role-your-own in that case...;-)
