Actually, that IS what he wants:
I connect SS in Undernet and SS2 in DALnet for example..
From DALnet's network i send a message (with a command like /msg) but the message must be said by SS in Undernet..
He wants to use SS (Undernet's nick) on Dalnet rather than Dalnet's nick, which is SS2.
That's where the problem is. If he wanted to send a message on Dalnet from Undernet using Dalnet's nick, that wouldn't be hard. But, sending a message to Dalnet using Undernet's nick isn't possible afaik.
