The only ans single database solutions you might consider at this moment (except MySQL which is already supported) is PostgreSQL ans SQLite.
I would switch my WordPress to SQLite. Thought SQLite has no full support for alter…
I remember some years ago (probably I was one of the first who tried to integrate bbPress with WordPress in a different language, fully localized integration [1]), and it was a pain. Now, years passed, I can see bbPress and WordPress rising and shining, but I wouldn’t pay anymore so much attention into their integration.
The main problem I/folks met when choosing between BB software and taking bbPress as a possible solution, is it’s lack of real BB features, like already mentioned quoting, nice fluid design themes… classic stuff which makes a forum software look accordingly.
I do respect the WordPress choices when it comes to design (including software designs and tehnologies), but if you want bbPress get over FluxBB (ex PunBB, which was sold and it is it’s main competitor), forget about Joel Spolsky’s thoughts, people are looking for something they got used to already. Bring options to core and hide them under checkboxes, but don’t apart them in plugins (at least until bbPress has no such plugin installer like WordPress has).
Dunno why, but bbPress still looks much like it was first time released by Matt after a weekend of smart coding. Time to grow up a bit. 
Just my 2 cents…
Glad we could help somehow…
Good luck!

Thanks for comments guys, I was just wondering how are the things going in bbPress camp, by the way I suppose the paying attention to this project is growing day by day so I can wish you nothing but luck… Ooh, and thanks of course.
Oh, thanks Trent…
I also did something, well not so great as you did…
I wrote about bbPress on my blog, including some of our reviews from here. The blog is of course on WordPress.com.
So far not to much responses… But I saw some referrers coming here from there.
Of, thank you guys for reply…
@Trent
I’m sorry, maybe I did not explained myself clearly:
I appreciate the thing that developers like the accessibility given by ajax, and are using this in their application, but the point was to leave the core functions that are for displaying content (like wp_list_pages(); for example in wordpress) outside of ajax.
You’re right wordpress uses ajax in the core but the templating part and the content is not affected at all (only the admin CP). This way we have ajax but only where it is really necessary.
Sorry for bugging, I do understand that my problem is not the #1 priority of the project team but I was thinking maybe there is any solution, thats why I reported that. Sorry …

Maybe the problem was in the marketing. bbPress was from the start advertised as perfectly compatible and easy to be integrated with WordPress. That is a great advantage, because WordPress is already one of the most usable publishing platform on the web, and people like everything that comes with it – as a result they took bbPress as an another plugin for giant. =]
I hope development team had a look on this thread:
https://bbpress.org/forums/topic/867
and on this:
http://forum.mootools.net/viewtopic.php?id=2337
Why?! Cause i’m not sure bbpress made the right choise on integrating javascript in the core of bbs! It is really hard to develop new templates especially to port some templates that use different ajax libs!
Let us give him some more time…
I wasn’t asking to remove the whole ajax staff.
I was asking to reduce it. Once we need only ajax http requests feature, why we should use the whole lib?
Can’t we just write a function for that?
It would be also great to had the possibility of including or not including any ajax libs in forums API, those already predefined and distributed with the bbPress or WordPress?!
Still unresolved…..
