See, I consider this a strength.  I would *never* type a command like
"plant pot plant in plant pot", and if I did, I would hate to think
that the parser would try to interpret it.  Of course, I generally
like descently fast-pased muds...this would fit into more of a MUSH-style
situation where you could spend more time crafting your commands.
I like a simple set of tools with which to interact with the environment,
that are never ambiguous and always easy for me to type.  The 'plant pot..'
stuff is confusing for everyone, player and coder alike, so I'm not sure
what the advantage is.
On the other hand, NLP has come of interest to me of late as we've tried
to make NPCs respond to communications from players.  Most muds have
a simple keyword thing, ie:

You say, 'Could you cast fly on me, please?'
>
The mage guildmaster says, 'Get out of here!  Quit wasting our time and go
buy a horse or something!'

One of my favorites from a mud I've played over the years...anyhow, this
is obviously quite stupid, as it just searches your say string for the
word fly, and would also respond to 'Someone kill that fly!'

We've done some basic stuff with trying to break the sentence into major
parts, which allows the mob scripts to easily determine insults, inquiries,
statements, etc.  Still all very basic; I'm wondering if any of you have
played with this at all?
