An USER caching some data doesn't seems needed to me (as its output will
already be cached. You mean an USER_INT caching data, right?

We already have this method in TYPO3 (since ever?), you just need to use
it: Table is cache_hash, t3lib_page::getHash and t3lib_page::storeHash
is the API to access it.
