my impression is that any client, who happens to be in the own network, is able to connect to a server and have an extended desktop at hand.
Is there a possibility to control such? Would it be not interesting to restrict the use of the service to ceratain users, where it requires a special action to add a new user?
Quite a few users are asking for the same and similar features.
Currently we are very busy with higher prioritized features.
The security features you suggested will probably not coming so soon.
If at all, then this feature will only be available in the pay version.
