Global Categories?

Hi,

I have just tested out the new easy blogging, and it's brilliant, I really want to use it on my site. It doesn't have the same problem with marketpress that I had previously, only allowing admins to add products to the cart. The only thing is I don't want to list the tags or categories, these have been a nightmare trying to explain to the members.

So I have found this tonight https://github.com/maugly/Network-Terminator/blob/master/mau_network_terminator.php

It's to add categories site wide, and I was hoping someone could tell if it was possible to use this to add product categories site wide?

Thanks.
