Ross: that link is not pointing to where I believe you might want it too..

I would suggest that perhaps you re-read what I wrote because I made it clear how I would deal with a product with multiple categories. It wouldn’t create 2 product pages.. the product would be returned in 2 different search/filter result pages.
Think of when you go to your supermarket. They only shelf a product in one place (unless it’s in a sale bin near the counter etc). Take Milk.. it could be categorised/tagged as dairy, white, bottled, carton, 500ml, 2L.. They have to decide on ONE term/word to shelf it under.. normally DAIRY. This would be the ‘section’ it is found in. This would be done in the magento back-end by the store administrator for their management purposes.
So regarding individual products and their permanent URL, as stated in my previous post, I would set it as:
Therefore, in dealing with multiple categories, this would be implemented in a search result/filter results page:
This is arrived at someone searching for milk and then adding the attributes to filter the results. Thus on the product page you could have down the bottom, found under “dairy farmers” that would link to:
domain.com/filter/manufacturer:dairy+farmers and would list all their products..
This would be found by search engines and would be indexed, as I agree with you about search engines not caring about if a page has a file suffix (.html etc). Thus the product would be found on multiple pages in search/filter results, as well as its ‘physical’ location (after following a link from the search/filter result page)..
Now about breaking the system.. that’s not my place at all to say because if it’s an issue, it can be changed. However, I don’t see any major problem? At the end of the day, all that is being done is a query and text can be manipulated easily enough.
I don’t obviously know if you understand the 2 points I am communicating (if because I am not communicating them well enough OR...). The first is saying the permanent URL is a ‘physical’ point: the product is found here (aisle 3, 3 shelf from the top). The second is saying that categories/tags/adjectives/descriptive words are used to find IF a store stocks a product (hi, do you sell white, 200ml, cartons of strawberry milk?).
Anyway, this is my opinion and it might not be even near a viable solution.
