I would be more interested why it doesn't work. I would suspect something has not been done correctly here. I would more info to assist. There is nothing new about the plugin system. We have been using this xml plugin stuff for the entire several years vb4 has been out.
Do you see the plugin code in the box when you hit generate plugin?
You can send me an admin login and ftp info to check out the files and what is happening if you want.
You can not just copy the xml to vb
as there is replacement stuff that happens in admin when you generate the xml to fill in proper information for your specific site.
