Bidboard vs CmisSync

A digital billboard to promote your startup

Promote your startup on a digital billboard. Out bid other people and get featured on the billboard the next day. The top 3 bidders of each day will get their product ad featured on the billboard the following day for 24 hours.

Synchronize documents between your computer and your enterprise file server (Alfresco, SharePoint, Documentum, any CMIS-compliant server)

It is like Dropbox for Enterprise Content Management!
For file sharing/synchronization, don't get a new server or rely on the cloud: just use your existing document management server.
Free and open source.
