It appears that the NodeTracker is a static class with a static
ParticleList as its collection.

If you attempt to use DynamicDom in a webserver environment errors can
error (e.g., the NodeTracker.EndTracking will clear the collection
which may be holding another user's Particles.)

Do you plan on making updates to this anytime soon? Do you have a
suggested solution?

BTW: other than that, the project/code is very nice. Thanks.
