Hi Steve
Yes you can have several hosts for your events and take their own payments. This is configured in the session template where they set the payment receiver email. We also support setting this via a community builder profile field.
With JomSocial you can either auto-create events in JEvents as they are created in JomSocial, import them on a one off or periodic basis, or if you want JEvents to lead you can show the events a person has created in their JomSocial profile page.
