Sorry for taking so long to reply to your Post Pete. I have a huge burden for missions, and as such Missional Living is a big part of my families' focus. There was a very cool sermon done by one of the pastors here in the Dallas Fort Worth Metroplex.
Here is the Link to his sermon:

Missional Living is one of the 5 focuses of the Village Church. They demonstrate it by being debt free, and they challenge their congregation to get out of debt. They teach parishoners not use any monetary bonuses in life to enhance their lifestyles, but to use those gifts to increase the mission of the Church.
I've been to a couple of services there - it has been compelling to say the least.
Thank you for the topic Pete!
I hope to hear more answers from other churches on how they emphasize the "missional" life in the US.
