Anthony, I would be interested to know how your testing on EasyCGI goes, can you please post back here. I am particularly interested to know if you get contents searching on PDF files working on shared hosting.
I am currently trying to use DMX 4 on Enterhost, it's all working except for the contents searching.
Peter, perhaps you could add a Hosting forum where we could post our results regarding success or otherwise using DMX on various hosting providers.
