Thanks for your reply. Your comments and paper are very interesting - good luck with your research work - I guess the end goal of this work is to enable a workflow controlled learning experience at university - nice idea.
My idea is Zoho with Moodle-as-third-party...a Zoho client would make REST calls to a Moodle 2.0 instance and receive a reponse with an XML 'file' which can be decoded within Zoho Creator.
I am not certain this may be possible, but I am interested in exploring it...it works for interactions between Zoho Creator and Zoho CRM.
One problem that I think is a major issue is that Zoho creator will only allow a GET, not a POST...and I gather that Moodle 2.0 only allows a REST POST....so I don't know how one gets around that.
Yes, that is correct Zoho orchestrating Moodle courses and users is the end-goal. We could make a solution available as a Zoho App.
As I said, I think Zoho is rapidly gaining popularity, so hooking it into Moodle would link two great forces of the universe
Regarding your comment about single-sign on. Obviously Zoho shares this with Google Apps (and Gmail too I think)...I presume it would be entirely up to the owners of Zoho, I presume, to set this up.
Also, if I did want to test this...does anyone know of a 'live' Moodle 2.0 instance that has WS enabled that I could try to link up with?
