Web service access

Our organisation is developing a Web Service which we would like to access using Matrix.
I am looking for an easy way to query the service and display the results.

Any ideas using existing assets/functionality or am I looking at a custom asset?

Sounds like a custom asset.

Thanks,
As I thought.

What's the service meant to do? More to the point, what are you wanting to do with the data returned by it? It may be possible to access it using XMLHTTPRequest in javascript.
