I have to take look at that.

At the moment my thinking was to store from search result brains the  
metadata that was needed, including the url to the object. With that  
cached data I would be able to create the needed views and would not need  
any object references or do special wrapping.

Today I looked more closely how Zope handles session data in Temporary  
folder and in Transience Object container in Transience objects, and it  
looks that I could use the same technique and objects without inventing  
the wheel again. I'll be only creating a Portal tool to offer api for  
managing the cache and to hide the actual implementation, so that if  
needed it can be changed to something else.
