Max Seats Per Ticket Type?

Adding a limit on ticket type may not be quite as simple as it at first appears. For example if you have seats of two types (i.e. VIP and Standard) you may have more than one price for each type (i.e. Adult and Child prices) so we then have two ticket types for each seat (i.e. VIP-Adult and VIP-Child) and it is the total of these two ticket types that we would be trying to limit.

I am working towards implementing Allocated Seating which would include an implicit limit for each area in the venue. This might be a way forward, maybe with the option of allocating a seating area rather than a specific seat.
