[FreeNX-kNX] Remote Assistance?

[Felipe Alfaro Solana]

Hello,

Does anyone know if NX/FreeNX is able to provide functionality
equivalent to that of Windows Remote Assistance? We are currently
seeking a Linux-based terminal server solution which allows an
administrator to interact with user sessions.

For example, let's say User1 opens up a remote NX session and finds
himself in trouble, like being unable to surf the Web. User1 can call
an Administrator for help. The Administrator will remotely attach to
User1 NX session and interact with it, in order to help solve User1
problems.

Is this possible?

Thank you very much.
