My comments we're aimed at the entity behavior, but rather towards the actual
imagery used for the entity. DIS is oriented towards military applications,
and the entity types (I'm talking images here) reflect that.

There's no question that DIS scales well - my comments above support that.
Just keep in mind that while behavior modeling of entities is great in DIS,
there is presently no accepted standard for environment/entity image
databases (scene graphs, whatever you choose to call a 3-D modelled
environment). *That* is the biggest flaw in DIS.
There are other problems that make using DIS directly unfeasible, such as the
'exercise ID' and 'application ID' fields used to separate simulations on a
single network. I *do* think that DIS concepts can be applied to VRML 2.0.
