I like the small footprint and performance of nginx on Dreamhost server
BUT:
It is a headache to do the htaccess rewrites.
I have an WP-MU with buddypress which is NOT running well
and I have installed status net that is also not running.

I have worked around with uncounted ways of re-writes on may posts and the dreamhost wiki, but it is not going well.
I would be willing to pay a reasonable amount to someone that has the experience or even the .conf file ready to get things working on Dreamhost server.
