We should probably rethink FlobFactories entirely
(as an aside, an answer to your earlier question that I hadn't time to
reply then: they currently only produce cells but they could easily also
produce more complicated objects, whose handle is the cell), because they
need to be

	- flexible and easy to use by views
	- efficient
	- simple to write (i.e. implementing as few methods as possible)
