Are pluggable brains only usable with SQL or is it a more general purpose tool than that? If it's general, could I get an example of using it without SQL?-)

They are general purpose in the sense that several products have the plugs necessary to insert a brain. ZSQL methods for the moment have a user interface for inserting a brain, but Catalog can also work with pluggable brains (albiet only programaticly, there is no UI at the moment for PBs in Catalog). You could create a ZClass that subclassed catalog and provided it's own kind of brain. After ZClasses bake a bit more, I would like to add add an interface to Catalog (and extend ZSQL's interface) to allow the admin to specify either a python class on the filesystem, or a ZClass. This way you could develop your brains through the web and then plug them in. -Michel
