Both projects are very exciting but wide adoption will not be possible until legislation similar to what you posted here is passed:

This will allow users to be free of capital gains for at least the smaller transactions where the crypto currency price has increased. Otherwise it will be a mess of paperwork and act as an added sales tax for bitcoin and other crypto users.
