So close with a mod_rewrite that changes underscores to hyphens for SEO. Can anyone close it out?

Based on what I've read, it appears that it doesn't have a huge impact one way or the other. That said, Matt Cutts (Google software engineer) just recently mentioned (http://www.youtube.com/GoogleWebmasterHe...3SFVfDIS5k) that while it doesn't make much sense to convert a site from underscores to hyphens, it would be best to use hyphens with any new development. Coupled with a client's request to use hyphens, it's time to figure out how to get CI to oblige.

Does anyone have suggestions about how to get hyphens to work with CI's class names using mod_rewrite? What I posted seems to work with any given URL segment except for the class name (first segment).

Also, thanks for the suggestion about using dots or plus signs. While they may save some time/overhead, as you've mentioned, they won't help at all for SEO purposes.
