While evaluating iFolder I just found out that it is not possible to share an iFolder with other users when the folder has been encrypted.

I managed to trick the Web Admin interface into letting the administrator assign a second user to an encrypted folder, but the second user was not able to open the folder even with the correct passphrase.

Does anybody know why this is the case? Is this a feature, is it necessary by some technical restrictions or is sharing an encrypted folder just something that hasn't been implemented yet?

It seems a shame that two of the most important features - sharing folders and encryption - will not work together.
