Notes		No multiple account solution so no access controls etc. single account only.					For Enterprise connect to Salesforce.com mostly web interface, unfriendly. permissions error (win8?) can't put files into sync folder.			For Enterprise				Personal Branding must extend with Workspace to "share files"						+Very nice client -mounts 2 drives??	win client requires .net 3.5
