7. Do not charge for lookups

In the current IWPS it believed that due to today's technological constraints, charging users is harmful to the viability of the service. There are several arguments for this belief:

• Micropayment technology is not available at the moment.
• Subscription services require either that the customer sign up to multiple search services or that the services are linked "behind the scene" with all kinds of bilateral agreements; both structures have unacceptably high overhead costs and increase the entry cost to the service.
• The current directory services protocols do not support authentication to a level that would seem appropriate for a service that charges.

Therefore it is strongly recommended that all lookups by users in the IWPS are for free. This, of course, does not limit in any way the ability to use the same IWPS dataset to support other services where charging may be appropriate.
