[CentOS] OT: Content system preferences, KnowledgeTree vs Alfresco

We're in the market for a new content system at work. Right now it's
between KnowledgeTree and alfresco. Mostly we're looking for something
with the ability to upload, tag with various meta-data, and share
among various other systems via webdav, cifs, etc.


Does anyone have any personal preferences or experiences with these
two products?
