There is a module waiting for approval on Drupal.org that creates direct links to nodes and users based on a UUID assigned by the   UUID module, in the form example.com/uuid/xxx-xxx-xxx etc.

Hi Folks

I use this pattern often, but have not found a module that does it, so I could just not know the correct name for things. 

* Create a unique key, normally an MD5 hash
* assign a set of data to the key and store this in the DB
* Create a url with this key in it
* When someone visits this url, load my stored data and do a bunch of things

I use this for obfuscated action urls, transactions and various other things, and keep doubting that I am the only one doing this. The url bit of this is just a use case, the main functionality I find myself building is the tool to create and retrieve datasets. 

Any existing module for this ?
