Just testing the beta secure-server version, and I'm impressed. Been looking for a more-secure replacement for our ageing FTP platform for a while, and this could be just the ticket.
Couple of small suggestions:
On the server, it might worth adding a "Deny Access" option in folder permissions. (which effectively would block the inheritance of access from folders above it) As the moment it's difficult to cater for the situation where someone has a folder within the FTP-tree which they object to being made externally-accessible.
On the client, if a user tries to upload a file to a readonly area, then the file remains in the transfer-queue with an error-flag on it, and it looks (to the uninitiated user) as if something has gone wrong with the program.. It might be better if the program popped a dialog saying "You are not allowed to do that!" (Or just change the wording of the transfer-queue message to read "Permission Denied" or whatever.)
