This is only a guess, but I'd be willing to bet there's more to this Blocknet <---> Ethereum relationship than just Dan being the point of contact for Ethereum, Boston.  

Simply put, Ethereum's DApp network and BlockNet's xbridge (decentralised cross-chain communication) would be a perfect marriage.  If this is the case, it would be fantastically beneficial for both projects.  

I suppose time will tell.
