I used routes to have SEO friendly URL´s. That works nicely, but I just have a fixed set of routes, and just a few of them use simple regular expressions.
You probably want to be able to have kinda dynamically mapped URL´s, where the admin can add new categories or products in the future, right?
Principally, I think this could be possible with routes and regular expressions.
I admit, finding the correct regular expression is not trivial.
