keystore need to be saved under the ETH address (not by meteor.userId)

[jellegerbrandy]

Now, keystores are set in localstorage with the following keys:

keystore-anonymous keystore-{userId}

the last one needs to become

keystore-{ethereumadderss}, so we can find it (in theory) also when we remove the meteor users from the equation

Not sure exactly of all the consequences...
