no - initial idea was that a USER_INT getting data from USER via TSFE-var.
So your hint is good, i'm not used with it. But storeHash could be 
"dangerous" if cache was emptied, then there is no initial data.
So if you want to be ensure you must call a method of the USER-Ext to fetch 
it.
This brings me to the idea of a small service an extension could have to 
deliver the needed vars. The advantage is that the service could be called 
everywhere.
