Acts 15 and the Law

I would like to hear a Federal Vision interpretation of Acts 15, especially Peter’s speech. Verse 10 of that chapter says, "Now therefore why tempt ye God to put a yoke upon the neck of the disciples which neither our fathers nor we were able to bear." I have not seen much discussion on this verse, and I think it presents some problems for the Federal Vision position of faithful obedience as doable. Peter here is disputing with brothers, elders in fact. Obviously then these who want to argue for law keeping and circumcision are not those who want faithless law keeping. These men from Judea are full of faith and desiring to pursue the law of righteousness by faith, but yet Peter says it is wrong to do so. He also clearly states that the law is a yoke that no one is able to bear. I would like to hear an exegesis of this passage from the "Law is Doable" perspective.
