For a small business with 10 users and a single server, it seems as though DropBox may be a good option to act as a file server. It would certainly remove some dependencies the server which would be nice, plus provide backups...
My question is, how well will DropBox fit into this type of environment? Are there any gotchas that should be considered? What about security? Does DropBox encrypt the files? How can you control who gets to what?
