One thing I am looking at is how to best create a library of world 
tarballs that can be used to populate a nfsroot (or hybrid of periodic 
tarballs + binary diffs to save space).  Then you could provide your 
benchmark in a standardized format (start/end/cleanup scripts, etc) and 
tell a machine "go and run this benchmark on every daily snapshot for 
the last year and give me the numbers".
