Hi Jeremy, thanks for reaching out, unfortunately the ability to sync to or connect to network drives is not currently available and is not on our short-term roadmap. We do have a product called "Files Connect" that is being released to GA in Winter '15 which connects Sharepoint 2010, Sharepoint 2013 and Office 365 repositories to Salesforce.

Our Files Connect roadmap also includes connecting to Google Drive. After that, we're planning to connect CMIS-compatible content management systems to Salesforce. I don't believe the ability to connect to or sync network drives is on our roadmap.
