After playing around with the Controller Layer I decided to do some evalution. You can find the outcome here: RendezCon.dmg.
It's sample code and an actual complete Application for browsing rendezvous. It's Panther (Mac OS X 10.3) only, as it is using the Controller Layer.
The distribution is binary and source under BSD-Licence. Please review the code and comment here on it. I want this to be good sample code for Controller and Rendezvous usage and will maintain it.
Share and Enjoy.
