I'm a bit afraid. I think we'll continue to see people layering their own things on top of [SOAP], making it more difficult to work. One of our engineers was at one of these interoperability get-togethers, and meeting with the Microsoft folk, and the Microsoft folk said that they have enormous interoperability challenges internally. They have 12 different Soap stacks that have been implemented in Microsoft. Just getting interoperability amongst those is quite a challenge. So yes, it is an issue, but people understand that it's critical and are focussed on it.
