Xpl0reR, what makes you think this can only be used by the very same machine hosting the script? it's simply BNC software coded in mIRC script, with uses on par with any other similarly featured BNC.
i made myself a similar script once for my work client once (on a client i actually used, so the 'ircd' socket in this snippet was actually a series of mIRC handled connections) so that i could IRC from home on the same connections.
