[Samba] send message with 'smbclient -M' to a certain user?

[Christoph Peus]

Hi,

I would like to use 'smbclient -M' to send a message to a certain user. 
This is not a problem if this user is the only one logged in to his 
windows box, but when he is using a Windows terminalserver with several 
other users logged in, every user would get this message, which isn't 
acceptable.

The windows 'net send' command offers this functionality. Are there 
plans to integrate this into samba's 'net' coammnd or into the 
'smbclient -M' command?

Are there non-samba tools, which offer this functionality for linux?

Thanks!

Christoph
