Flash seating plan

Hi Guys,

Not sure where to ask, but Im building a database of members and events and would like to integrate it with a seating plan. Is there a basic application, whether its open source or paid for already built in flash that has an open api so I can communicate the members through xml?

Any help would be much appreciated. It doesn't need to be too advanced, but would like it to represent some graphical way of displaying tables and members associated to the tables.

Many thanks for any help
