[Zope-dev] Caching ZCatalog results

I'm curious, has anybody played around with the idea of caching ZCatalog results and if I submitted a patch to do this would it be excepted? I quickly coded some basic caching of results on a volatile attribute and I was really surprised with the amount of cache hits I got (especially with a Plone site that is a heavy user of the catalog) -- Roché Compaan Upfront Systems http://www.upfrontsystems.co.za
