OK, I'm no expert at Steem development but I'd definitely be interested to keep an eye on this project as it goes on.

I don't think the reluctance of some to engage with the EU is warranted to be honest.
Yes there is a lot of bureaucracy and politics involved but in the end this is an opportunity for the EU to recognize the value of the blockchain.
Going for an opensource solution would also ensure transparency.

The licensing on any technology developed for this is also interesting.

An organization like the EU would definitely want a contractual relationship to provide maintenance and support of this blockchain.

Anyway, I'm sure there are many non-technological points to clarify, including legal.

It will be interesting to see how this shapes up!
