what permalink structure do I want for a Buddypress multi-site network?

I wish to setup my new site correctly on a VDS with GoDaddy, and I intend to create a Buddypress/Multi-site network with many of the bells and whistles you offer.

Please, give me a solid permalink structure, so that I can get off to a good start. I gather it should be pretty permalink ready.

Many thanks- had problems teasing out the correct solution in the forums,
