Taking over Product Catalogue sample site

As a part of some free-time developing I took over Product Catalogue sample site (which I saw was requested for updating by someone).
The first stage - direct upgrade to Sitecore V6 is done:
http://trac.sitecore.net/ProductCatalogue

If you have ideas or wishes for this solution, please mail them to me at dv sitecore.net and I will continue improving it with pleasure.
