Building a global community site.

Here is what I am building:

Site for a global community of participants and practitioners.

-Shop selling products
-Registration for events – events publicly advertised but participants have priviledges access to groups and resources.
-Community with forums, groups and restricted access to resources
-Memberships (paid) granting access to restricted content, forums and groups.
-Split payments for a reseller model where practitioners can create events, name their price and a royalty goes to site owner from registrations.
-Document management linked to groups, events and memberships

Country based listings of members and events

Group specific products – products restricted to group members.

After a lot of research I have the following plugins:

Buddypress with duddydrive & bbpress
Woocommerce
Events manager
s2member framework

These integrate to some extent but the whole thing is quite complex.

Any insights for those who have built something similar? More comprehensive plugins…

Thanks in anticipation
