My main responsibilities are checking that you are a local software developer, getting confirmation from you that you will make good use of the subdomain, pointing your subdomain to your specified NS server(s) and updating as need be and answering questions, all to the best of my abilities.

You agree to abide by the rules, terms and policies that filter down to you from TTNIC with the added restriction that your subdomain is only for you as a local software developer for use only for proper developer related activities - https://www.nic.tt/agreement.shtml - This is the agreement that you read and agree to when you purchase a domain name directly from TTNIC, except now you are signing up under the manager of .devs.tt for free. Please note that you must not use this facility for anything illegal including porn, phishing, spam, malware and any such things. You will be removed immediately. 

I do not think this is being done by any other cTLD. If you know then let me know. I would love to learn from the experiences of others especially as it relates to a SLD for local developers. This was an idea I had given to MDT for the DHub and that I have followed up on.
