We're running applications in up three or four different environments and I don't want to maintain instance specific configurations within ZCML. Either we pass such informations through environment variables or the database connections parameters are read from a configuration within the instance configuration.As long as it can also be specified in the code, that way people can build UIs to set up the connection. Perhaps that's what you mean by a "configuration within the instance configuration".The way I use collective.lead in my book is to have it look up the database settings in a local utility. That utility is editable via a control panel page in Plone. I suspect that it'd be quite easy to do something similar where the settings were deferred to a global utility configured with ZCML or looked up in a config file of some sort. Once the config is available, it's all about calling getUtility() to get hold of a database connection/session.
Possibly a sane and clean solution but way of over-designed. I am interested in simple and robust solutions that work and not in a solution that adds more and more unnecessary layers just the sake of having them :-)
