Approve and second Mario's comments. Spencer has been a great assist when EthereumJS was failing some of the hive tests in terms of trouble shooting and giving us test beds to work with.

I worked with Spencer on porting ethereum/tests to python and making more tests. He did a lot of great work and is very pleasant to work with
