Cheers, yeah there was no need to rewrite the book on Intuiface. The process is so simple with the examples you already have, and the page I linked to. The issue is making Drupal output the data you want. 
I have a 6 month break after Christmas from work, so I’ll aim to do a full bloown tutorial on it then, that could be used for your reference, or happy to assist in setting up a Drupal example for/with you.
