I started to search for more information on what i was doing found a good posting from Steven Swafford On Using Application Cache for viewstate.

His post also refers to a asp.net podcast that talks about the same thing. It is good if your application is on one server or Your farm is using sticky session. But it is still a good idea, i emailed him asking permission to take some of the code and create a Viewstate Storage medium for ViewStateEliminator.
