These look good.

I've made a first pass at creating a patch to use this (for 
http://trac.wordpress.org/ticket/1476 patch also attached there) which 
will display a message on the dashboard the returned version is 
different from the installed version.

I've also attached a screenshot of how it looks at present

Comments??

I would have had this done a bit quicker if I hadn't been offline for 
nearly a week!  :( -
