Well when I see it in action I realize its far to slow, so my suggestion is to add some sort of an option that doesnt make the DCC active when opened:
var %active $active
dcc chat $nick
window -a %active
is too slow or inconvinient since it first pops up the window before returning. Heres another idea:
dcc chat -u $nick
where u might mean not activating it on open
