Filepicker.io launches Alfresco, WebDAV, & FTP integrations

This is our first shot at adding enterprise content platforms. Would love to get the community's feedback.

i realize it might be slightly out of scope, and a less common use case, but an FTP integration that worked the other way around (users can upload to a filepicker hosted FTP and it sends a postback to my app) would be enough to get me to subscribe. cool service.

What protocol do you guys use to talk to Sharepoint?

Alfresco and FTP I get, but why WebDAV? I cannot think of anything which still uses this protocol, no service nor enterprise deployment.

Alfresco eh? I am debating between Liferay and Alfresco currently. Anybody got some useful advice for me? Thanks!
