In no particular order:

• Use A-Match to support the Warren and Joccasta demos on the web.
• The Unregister and Update functionalities do not provide any security. Users should not be able to modify or delete the advertisements of agents other than their own. One possible solution would be, when an advertisement is shown, to suppress the display of the contact person and their email address. This information could then be used to verify that a user is indeed working with their own agent.
• Implement a book search agent for A-Match to allow one to search for the cheapest price for a book among web booksellers.
• Use A-Match as an infrastructure to experiment with new types of middle agents and (hopefully) with load issues related to middle agents.
• Unregister and Update functionalities merely augment the Browse functionality. Were there large numbers of registered agents, a user could use the Find function to return an abbreviated agent list. However, there is no analogous function for dealing with unregistering or updating an agent. Such a function could be implemented.
• Provide the user with some method to explore the ontologies that are currently available.
• Replace the relatively simplistic matchmaker matching methods with the more powerful Larks system.
