plenty of suppliers with plenty of heterogeneous systems and
software...all set within a more closed 'extranet' type environment.
They are not being driven at the 'web' layer where 80% of us live,
though things such as REST are growing up from the grassroots and things
such as WS* are growing down, hopefully they will meet up.

the next primary selection characteristics for web services (for the
future) would be;

- perform software to software integration, underpinning true machine to
machine collaboration (e.g. along with commodisation it brings)

- application composition enabled using real time service discovery and

as for seperation of content and presentation...not sure if perhaps its
confusing to use the term presentation where 'interface' would do, along
with 'content' where 'data' would....slight differences in semantics
