Interesting article. Just thought I'd mention one of our mechanisms we use at work already generates RSS out of SAP R/3, specifically related to orders and order proposals. Works really well, the satellite apps can consume the data using standard tools. I've also been looking at ways I can use the RDF characteristics of RSS to enhance and extend the meaning of what is being pushed out (relationships to other business entities, and so on).

I think there's a lot of mileage (and fun) to be had from introducing REST and RDF ideas to the business data and functions that R/3 oozes. (I had mentioned some previous thoughts on my weblog earlier this year too).
