Webdav contacts

[blackcrack]

Hi,

i use openmandriva (.org) (the real successor of Mandrake but in the hands of Community now)
as my webserver blackysgate.net and i have there running owncloud
and use it for different web applications and for my Thunderbird also,
would be nice if be able to use webdav's contacts in Mailpile
(i dont know if this currently already possible but short ask cost nothing i guess :) )

best regards
Blacky
