I am interested in hearing whether anybody else has tried to...

Create a user account in a moodle system on the fly by REST API calls.

I understand that someone in the Moodle camp was making a REST API Web Services module available within Moodle 2.0. Refer  http://moodle.org/mod/forum/discuss.php?d=33521

It would be great if this could be accessed from Zoho Creator using  many of the same techniques that are used, say, to make calls to Zoho CRM.

Love to hear from anyone who has made headway in this area.

Regards, 

Liam.
