Cloudfogger[0] has an interesting solution. Anything within the cloudfogger folders gets encrypted before it can be synced with the cloud service. It also changes the filename to add its own extension. When you open a file, cloudfogger uses the password cached on your system to decrypt and then run the file, providing a fairly seamless experience. The one main problem is that it's not an open source client, which seems like the ideal solution. [0] http://www.cloudfogger.com/en/ http://www.cloudfogger.com/en/ Edit: Why downvotes?
