WP-Syntax should take all of 10 minutes to port to bbPress:

I have a “Syntax-Lite” plugin in development that is less than 1k and uses PHP’s built-in (high speed) highlighter but only works with PHP code of course. It also won’t be available for quite awhile as I don’t have time for bbPress projects these days.
