Hilton and all,

Quick FYI -- we actually have a list of all known DSpace installs 
worldwide off the DSpace webiste (under the "Who's Using DSpace" link).

http://www.dspace.org/index.php?option=com_formdashboard&Itemid=151&lang=en

So, if you are ever curious to see someone's install, it's highly likely 
you can find a link there. This list is also searchable, and you can 
filter by database type, DSpace version, OS, etc.

- Tim
