I just found an article at http://blogs.msdn.com/mszCool/archive/2004/06/14/155420.aspx that goes really well with my old article about using reflection to build plugins.

Basically the article covers how to change the permissions of the appdomain to allow only permitted actions - a great thing to do if you want your users to be able to build the plugins!

(Update five years later in 2009: Also I forgot all about this article and did my own example here http://www.nullify.net/ViewArticle.aspx?article=315 )
