If I understand you correctly you have mu installed with the subdomain option and you want to run the bp home theme on a subdomain. That’s not a problem. Just activate it for that subdomain’s blog.
That’s about all I understand in your question or problem.
I activated it for community.domain.com but the links kept going back to domain.com not community.domain.com within its own theme. I cant find anything to insert the static links to keep buddypress theme within its own subdomain itself.
What links keep going back to the root domain that you think should not? You have to be specific otherwise I’m not going to understand.
Let me explain a bit more clear about this…
* Home
* Blog
* Members
* Groups
* Blogs
As you can see those links under BP Home theme. If I create a community.domain.com to run BP Home theme and anyone of us click on individual profile then it takes us to domain.com without community as subdomain. Even it happened to left side menus that took the whole thing back to main domain.com instead any links to be strictly within community.domain.com itself.
Thats why I need to find where to edit the static links to point out on community.domain.com instead fall back to main domain.

Any progress on this?
I’d like to install BuddyPress on a subdomain too (the top domain is a public website).
Would be an awesome feature! 
This thread points to a domain mapping plugin for wp.

Thanks burtadsit. I’ll take a look, I’ve used the plugin before though and I’m not sure if it’ll achieve what I’m looking for.
Essentially the issue is that http://www.domain.com is a public website and we use http://staff.domain.com as an intranet (it’s just a members only blog).
What I’d like to do – although I haven’t yet investigated setting up BuddyPress as a closed system – is run BuddyPress at http://social.domain.com.
The problem is, when I do this is works perfectly except that it renders all links as though they’re from the top domain.
So, as jedbarish mentioned, none of the following links work:
* Home
* Blog
* Members
* Groups
* Blogs
As instead of going to http://social.domain.com/blog they point to http://domain.com/blog which yields a 404.
