The organic groups module does what you want I think.

http://drupal.org/project/og

I use it in a very similar way to what you describe for the ERP module 
set we're building that is nearly ready for release.

In our case, each "customer" is also an organic group, which means we 
can give a customer user access to their own posts, but not any of the 
other customer groups/posts.

Managing such a large number of groups at the bottom of each node is the 
next hurdle I'll be submitting patches to the og module for ;-)
