Zork on IM

This link tells how you can play old text adventures with an IM client. Pretty cool.
Infocombot:> You are in a clearing, with a forest surrounding you on all sides. A path leads south.
On the ground is a pile of leaves.
NiktoIM: get leaves
Infocombot: > Clearing Score: 0 Moves: 6
A grating appears on the ground.
Taken.
NiktoIM: open grate
Infocombot: > Clearing Score: 0 Moves: 7
The grating is locked.
I think IM is a great platform for the right kind of game.
