Important SEO feature

Hello Guys
I should first say Thank you for your hard work as this is perhaps the best open source Ecommerce site out there. I am have very impress with amount of features and progress from the very first version to now.

I am not entirely sure as if this specific feature has been request or not regarding SEO.

I am a heavy user of drupal and have been involved with few of the module for V6.
drupal has a module called nodewords. This make drupal and in addition their ecommerce module Ubercart very powerful specially for SEO. they feature of that is basically you can define as what keyword you like to have for each Node("in our case it would a page or product"). You can define many things such as Meta tag, titles , url renaming.

I think URL renaming and few other SEO option integrated with 1.3.0 is great but having option for each product to add also not only meta tags but also in addtion to meta keyword , if we can have the following added, it would make the ecommerce more powerful:

<meta name="copyright" content="xxxx" />
<meta name="DC.Title" content="xxxxx" />
<meta name="robots" content="index,follow" />

also drupal has a module called Pathauto("http://drupal.org/project/pathauto") which helps to rename the specific page("node") to what you like.
for example a product named Mac book pro 2100 , you can have when you go to view the product detail to rename the url to also like mac-book-pro so that you get something like http://www.xxxx.com/xxx/mac-book-pro.

this also help SEO extremely
