[Zope] Is there any plans to combine harvest with catalog?

[Jay, Dylan]

Well, as I understand it, the idea of harvest was to provide standard
interfaces to any kind of data. Each site had brokers that did local
indexing and exposed an interface to other search engines. This allowed
general search engines to index very specific kind of data. Harvest WAS
academic stuff and I'm not sure what happened to it. But supporting any such
brokering sounds like a good idea to me.
