There has been some discussion about the deployment model for the upcoming MidCOM 3 MVC framework for PHP and Midgard 2. My suggestion was to enable WebDAV on all MidCOM servers so content structures, configurations and templates could be moved between them with simple drag-and-drop.
This week we're having a MidCOM 3 coding sprint, and now we can already mount the MidCOM site, and with some clients also edit content. Locks also work transparently between WebDAV clients and the web editing interface.
WebDAV serving logic is implemented using PEAR's HTTP_WebDAV_Server.
More functionality will follow...
