@John
First I want to thank you for bbPress as I use it a lot. 🙂
I had same question like OC2PS from long time and after reading your answers, I still feel an urge to take this discussion ahead. IMHO what OC2PS suggested is intuitive.
With references to your answers:
> Taxonomies don’t have metadata, to allow for topic & replies counts or latest content
(Not one of best suggestion) Taxonomy-meta can be stored in an extra mysql-table. I wish like many other this to be part of WordPress core though (ref)
Once we accept overhead of extra DB table, other things seems easy.
> Comments don’t allow for attachments without some major work
Comments already have commentmeta. May be we can use it to store array of attachment_id.
Off-topic – By the way I did not find attachments support in bbPress out of the box? I am using a bbPress plugin for that. Am I missing something here?
> The API for custom post types is farther along…
Agree. 🙂
Post-revision is an example which I guess used internally to track edits to replies.

While the outcome bbPress is good in reality, it just feels off-beat to have 3 custom-posts.
IMHO, going with 1 custom-post+commets+custom-taxonomy way might have made themeing part easier…
Thanks. I was looking for a thread like that.
May be I choose wrong keywords to search.
I will continue there…
chrishajer is right about issue with ‘slugs’
only false option works… 
$bb->mod_rewrite = false;
are they rectifying this in next version??
