Acrobat.com Information Details Home Page (and pages below) My undertanding is there is a total of 5 Gig storage for this service each account. There is a nice intro RIA style at the top of the info details page.
Now if all that wasn't pretty cool then consider getting this package in an AIR application! (I will get this running after doing the blog post.)
Also don't forget to check out the connect users group at the following link.
