My view is that any sensitive data handling should be done via SSL, whether it is done over the wired or wireless networks, rather than relying on data encryption on portions of the intervening network. With the right tools, there are ways to capture some of the network traffic even on a wired, switched network, so it's best to always use SSL when transfering data between systems. We do this as a matter of course for all of our UNIX server-to-server transfers, backups, etc., and our client-to-server operations as well. I don't know what it takes in the Windows client/server environment to use SSL, e.g. for mounted file systems, but it's worth considering. One alternative would be to run a VPN server with encryption on your file server, and use that for all remote access via wireless and remote access. And yes, to answer your question, we don't provide encryption on the wireless system, outside of the authentication, which is done via SSL (https login page).
