BuddyPress.org

My apologies if this was even remotely covered before, but I can’t seem to find another thread or Google result for my desired solution.

Currently, new blogs in WP (under directories-mode) show up as: example.com/{username}
And Buddypress URLs are: example.com/members/{username}/action

I’d get the WP blogs to appear as:
example.com/members/{username}/blog
example.com/members/{username}/blog/2010/08/postnamehere.html
example.com/members/{username}/blog/pagenamehere.html -or- example.com/members/{username}/blog/page/pagenamehere.html

Though, if somehow possible, maybe make the pages show up without the “/blog” tag:
example.com/members/{username}/page/pagenamehere.html

I’m pulling my hair out trying to figure out how to achieve at least the first part of the examples above. I know it could potentially create long URLs, depending on the permalinks structure, but I’d rather keep everything neatly under as uniform as possible. I’m a permalinks-fanatic like that. As of now, I’m only in the development phase, so I’m willing to change whatever files needed to gain this functionality. I have WordPress 3.0 with multisites enabled (currently in sub-domains, but will change to directories to test any theories), and the latest stable Buddypress is installed.

If there are some really severe (showstopping) side-effects to even attempting such a scheme, then by all means, let me know in detail. “I don’t prefer that” is not a valid reason, though.

Sorry for the huge post, but a thousand thanks in advance for the assistance! I realize a lot of this could be achieved by paying someone an insane amount of money (and if I really must, I can), but I’ll never learn that way.

(PS: Would there be a way of forcing all blogs to use a certain structure, with no possibility of changing it?)
