Your suggestion is added to wishes list, but note, that brute-forcing even a simple password over network will take years to perform. So, if somebody don't know password and password length is greater then 6 characters there is definitely no way he or she can suggest it.

Brute forcing... not true that it will take years. Since there is no perceptible delay imposed by the software, attempts are only limited by network speed, and these days most of us are on pretty fast connections. You could try thousands of words in a couple hours. With a long list of potential radmin hosts avaialable courtesy of your port scanner, anyone with half a brain would probably be able to hack 10-20% of the available hosts.
You don't need to try every single combination in the world to brute force a password. You use a dictionary of common words first. Sure, you can blame the user for using a guessable password -- but since you guys have said you won't ever make encryption optional because users are stupid, I would think that this logic ought to be continued to assume that users will not always use good passwords either.
Building in a timeout is an extrememly simple and common solution to prevent brute force attacks. There's no good excuse for not having it.
