Can you send them to a person in the US, and that person sends it to dave.
Please! No one even TRY this!
This is what gets people sent to prison, no exaggeration. The US can and will charge and extradite the foreign receiving party as well.
Once something is classified as military hardware, the US has amazingly long arms. Never mind that the memristor is a fundament element, our laws, nor our congress persons particularly care.
Is it illegal to export something that hasn't yet been given an export classification? Would it fall under a generic classification until determined otherwise ?
In this particular case, where Defense dollars have been invested in development for a military application, the only safe route to export is to submit a request to the US State Department and ask for a letter that grants an exemption.
The wrong thing to do is to try and export without a clear disposition.
Just to give you an idea of how arcane and restrictive US law on military hardware is, as a US citizen, I can purchase the latest night vision equipment (if I could afford it). However, it is illegal for me to hand such a device to a non-US citizen and permit them to view through the night vision, even if we are in the US and I have no intention of selling or exporting the device. At that point, I have effectively exported the knowledge of what that device can do and have broken the law.
So, when in doubt, ask the State Dept (or regulating authority) for disposition before transferring technology. Most of this stuff is explicitly detailed as part of ITAR, but there's some stuff, like this memristor, that have likely not been addressed yet. I just would not assume that this particular device is "generic" when the DOD might feel they own it at this point.
Sorry for the "Danger Will Robinson!" posts, but this can be tricky business. I think if you're upfront and honest with State, you could get approval easily enough. Sneak around, and there's likely to be little forgiveness.
