uploading files to a webdav SSL enabled server

[rbt]

Has anyone used pure python to upload files to a webdav server over SSL? 
  I have no control over the server. I can access it with all of the 
various webdav GUIs such as Konqueror, Cadaver, etc. by using a URL like 
this:

webdavs://dav.hostname.com/user_name/uploads

My goal is to upload files automatically with a python script. The 
server requires authentication over SSL which I can do with urllib2 like 
this:

def auth_against_url(url, username, password):

     # This is a slightly modified version that I found here:
     # http://simon.incutio.com/archive/2004/07/15/instant

     import urllib2
     import base64
     request = urllib2.Request(url)
     b64 = base64.encodestring('%s:%s' % (username, password))[:-1]
     request.add_header('Authorization', 'Basic %s' % b64)
     try:
         f = urllib2.urlopen(request)
	print f.read()
	f.close()
	return True
     except urllib2.HTTPError, e:
     	print e
         return False

auth_against_url('https://dav.hostname.com/user_name/uploads',\
                   str.strip(raw_input('Enter User ID: ')),\
		  str.strip(raw_input('Enter Password: ')))

If urllib2 supported webdav, I think I'd be in business, but it doesn't. 
Any one who can provide pointers on this? I've googled around to no 
avail. I've began playing with Perl's HTTP::DAV and somone reccomended 
PHP's curl functions as well, but I wanted to try this in Python first.

Many thanks,
