@iceziin:
it already works great if you configure it properly. MSN is equally bad at sending files if neither user is configured to properly send-- the only difference is that MSN allows file transfers to go through microsoft's servers when no direct connection is established allowing for a *much* slower transfer but reliable connectability. IRC *cannot* do this, and therefore mIRC cannot compete. The slow-transfer through msn sucks anyway, so there's no point in trying to emulate it.

@foshizzle:
what's run through the IRC server? DCC does not depend on an IRC server to work.
