Artifical Neural Networks are a bit simplistic for anything i would use
for AI in a mud. Perhaps the neural net could be used as a tool for a=20
rulebased AI, where the NN is used to try and identify 'situations' where
a given ruleset would apply, but i cannot see how NN could be accounting=20
for AI by its own.
Specifically you need to 'display' the events in the mud intelligently to
the neural net. The better you port your event into the 'problem domain',
that the network is trying to solve, the better you probably will get the=
network to perform.
Another problem is CPU power, as someone else also commented on, training
or using (which is less demanding than training) the networks of thoustan=
of NPC NN's would be very demanding, even on today's hardware.
What you perhaps should think very hard about, is where in your AI you wa=

just because you interconnect a few thousand neurons.
As before, you could try using the neural nets for guessing wants/needs o=
threat/non threat, friend/enemy and other hard-definable feature, and use=
these ovservations later on.
Then of course you need to train the network, you need a set of situation=
that you can display to the network, and then tell it if it performed
correctly or not. This may be, if possible, to train the network on-line,=
that the network at one time may predict some situation, and then at a la=
time be able to definitively tell if it predicted right or not, and that =
learn from its mistake/success. However, you can also set up a set of cas=
offline and start by training on them first.

Another idea (which better deal with time-sequences) is hidden markov mod=
