Hi Jessica - the primary difference between Offer and Ticket is that  
the Offer is only *proposing* as set of
permissions (and constraints etc), whereas a Ticket *allows* a set of  
permissions (and constraints etc). The latter being for the actual  
holder of the ticket.

Is that clear? Perhaps we need to update the model...
