[Zope] ZClass Distribution Question

Hello, I've developed an online app using ZClasses for components... After seeing some threads arguing about ZClass quality, I have a question. I'm planning to use the Distribute function of the ZClass to move them to my ZEO setup, eliiminating the possibility of editing them in production. Are there any known problems with the Distribution mechanism... I noticed it generates an unreadable binary file of some kind. Do ZClass Distributions with higher versions replace former versions well.... any lost references, etc. Just need some ZClass confidence from someone who's been there. I am commited to ZClass's, at this point, just need constructive advice. -Jon
