I don't think you read my comment completely. No, there really are no quality or useful telnet clients out there, especially none for playing MUDs. Putty sucks, and Window's telnet client is functionally broken.
mIRC has everything it needs to create a Telnet window that can be used for a playable MUD. And people who use IRC are 98% more likely to play a MUD than people who don't use IRC. It only seems practical and accommodating to add this feature.
And as I expressed, no, it's not feasible to script a telnet client in mIRC. It requires external DLLs and hacks and is very slow this way. Hard convincing someone to join you on a MUD if they have to download extensive crap and hack their client. The major problem here is MUDs love ASCII art and spacing, which a script alone cannot handle.
If given the choice of removing /finger in exchange for /telnet, I'm all over that.
Additionally, mIRC's scripting language would be superb in a Multi-User Dungeon game.
