Suggestions, I've got in spades:

HTML::Tag::*

1. ::Filter (might be confusing)
2. ::Cleaner (cleans tags? maybe not...)
3. ::Remove (removes tags... accurate!)
4. ::Sieve (keeps some tags, removes others, like a filter in a way)
5. ::Restrict (restricts HTML to allowed tags)
6. ::Replace (replaces Tags with other data)

I've bolded my two favorites. Those are my suggestions. The jury is out on whether they are good suggestions, but you did say that any suggestions were welcome. ;-)
