embedding a python interpreter is the way to go.  If you need
an interpreter, this is the one you want. :-)

Right now there are problems w r t security and doing this.  The
pypy rewrite of python adresses them with the 'Taint' object space,
because we want to be able to embed pypy everywhere too.  So 
while embedding python is what you want, you may not be able to if
you want to make this a commercial MM game, for instance.

Once Europython is over, I intend to (collapse and) have a vacation.
One thing I was looking at writing was a generic 'quest solving'
library, for text type quests.  Think infocom games.  We want
'throw pumpkin through window' to work, but only if the window
is open.  We also want 'defenestrate pumpkin' to work, and
'toss pumpkin through window'.

I am wondering if this library:

http://nltk.sourceforge.net/

could help with the natural language bits, but I haven't investigated
this.  One thing I do want to do is get thesarius support in there,
from some online thesarius, so that people who type 'toss pumpkin
through window' won't fail because I didn't make toss a synonym of
throw.

At any rate, this is what I have been thinking, at any rate.  No code
yet.
