Quite simply, at least in my eyes, if you have a user that needs accessed to more than 1 or 2 published Application, it's easier to just do a custom Application set then it is for a user and administrator to keep track of, let's say, 10 custom ICA's. There's not much overhead difference really. -----Original Message----- From: Bergman, Bryan L.

I guess I am looking as to why someone would choose one over the other. Also, what are the fundamental differences, such as performance, overhead (if any), etc. Thanks in advance. Bryan
