I'd just like to say that **this project is very good news**, for both Nim and Ethereum.
* * * I've been critical of [cpp-ethereum](https://github.com/ethereum/cpp-ethereum) being GPLv3, which means not everybody can use it (for either practical or philosophical reasons). As always, I personally urge using [a copyfree license](http://copyfree.org/standard/licenses) for the Nim implementation.
