Personally I think the easiest solution to the percieved "security" 
issue (personally im not conviced you can really call it a true security 
issue) is if you are going to create a long lived cache (i.e. on disk or 
such like) that before you decide on your definative value to cache 
generically (i.e. client/ver) that you use the results from several 
different JIDs (e.g. 3 or 5 or something) and compare them, if they are 
all the same it should be pretty safe to create a generic cache for that 
tuple of client and version, if they dont all agree then you can then 
consider those results and potensially poisoned or buggy and cache using 
the jid/client/version tuple instead, simple and easy, no need to get 
all het up about it.
