That would be amazing - ERRest certainly is powerful - you have to get the idea about implementation, but once you do I can see there are lots of tricks and patterns to take advantage of.
I'm interested in exploring the interaction with D2W and HTML/Components, as well as crafting precise filters, adding authentication layers and making safe qualifier APIs
Glad to help as I move along!
