Hi David,
Thanks for checking out our plugins!
This is indeed possible using Community Tickets. You have the option to set fees based on a flat fee, a percentage, or a flat fee and a percentage.
As far as distributing payments goes, you have two options. You can either collect all of the money and then pay the organizers however you choose, or you can split the payment, in which case you will need to set up a PayPal developer account and your organizers will need to enter their PayPal info when they create an event. With the second option, the fee is automatically sent to you, and the rest is sent to the organizer.
This article has some great info on setting up payment options and collecting fees.
If you have any more questions, just let me know!
