building a true community of 200 sites

[Pardner Wynn]

I'm attempting to figure out if it is possible for me to set up a 
Frontier community that will host 200 individual churches that want to 
share specific info across sites...

Each church wants its own site. Okay, that seems easy enough even for a 
total newbie.

But can Frontier do this following, and if so, is there any 
documentation available since I'm a newbie at Frontier (but otherwise 
fairly technical):

1) They want to to share the registered user list. "Join one site and 
you've joined them all" is the goal. Registered users of 
ChurchNumber001 do not want to have to manually re-register at 199 
other sites in order to access the functions reserved for members -- 
among other things, they'd probably end up having to pick something 
like 20-30 different login names for different sites if their name is 
common and already used on other sites.

2) However, just because "Bob" is an Admin for Church #1's site does 
NOT mean he should be anything other than a normal member for churches 
#2-200 (unless they individually manually grant him that Admin status).

3) They want to be able to create certain shared info. The simplest 
example would be Recipes. Each church would post "their own" page with 
their favorite recipes. But they'd also like to have a button that says 
"show me ALL the recipes for ALL the churches."

4) Similarly, they'd like to be able to Search across sites. As in 
"show me all the 'fried chicken' recipes".

5) Having some sort of aggregate calendar of events, perhaps at some 
top-level site, would be very very desirable. "What's going on anywhere 
this weekend?" It would be nice not to have to browse 200 sites to find 
out.

I hope the answer is "that's easy" and I simply missed it in the docs!
