Thanks for all the supporting comments and involvement with Mango M2M.
At this time, the planned implementation is fairly rudimentary, but extremely viable. This will be available in the next release.
It will not be able to meet the requirements and suggestions that you outlined below. However, if this is a feature that has real use to you or your business, we would be interested in following up with you on this to see if there's an opportunity for us to do some sponsored development to enhance it to this level. If there is, you can contact us at this page: http://mango.serotoninsoftware.com/contact.jsp
We appreciate your continued interest in Mango M2M.
