Yes, i have the written response. I was never told specifically that I could not share this but Im honestly not sure what the rules are. It would be good to publish this if it encourages others to post their work. So unless anyone has any warnings as to why it should not be published I'll strip out any personal/contact info and send a PDF to the list.

Hi Graham- Did you get a written response and if so would you mind posting it online? -RM On Saturday, February 7, 2015, Redacted sender gnsortino@xxxxxxxxx for DMARC <dmarc-noreply@xxxxxxxxxxxxx> wrote: Hi aRocket - A few months back I inquired about the possibility of posting an igniter online as open source. After some consideration I decided to follow up with the State Department to get an advisory opinion as to whether this would/wouldn’t violate US ITAR regulations. The process took some time but this past week I received an ‘ok’ to post online. The scope of the advisory opinion is fairly narrow in that it applies only to non-flyable less than 200 newton engines (since this is what I asked for) but the engines I build currently fit into this category so I’m happy for now. I’ve since gone ahead and posted STL files on Github (https://github.com/gNSortino/OSREngines/tree/master/Engines/2014-GOXEthanolRegenEngine) under a creative commons license. So feel free to use, study, modify, etc... I hadn’t thought of using GitHub to post any non-code resources but after seeing how nicely the PSAS site was laid out I decided it was better at version controlling things like CAD and design files then a Wiki or WordPress site. I’ve also just sent my v2 regen to the printers and am planning on testing that this spring. Once I’ve had a chance to test I’ll post that info as well. Kind Regards, Graham
