Both progressive and emerging?
Look at someone like John Shelby Spong: pretty radical in what he says, yet he still wears the dog-colar and purple shirt of a bishop. He looks entirely like a bishop.
Similarly in Unitarian congregations: the theology might be off the wall, heresy of heresy, yet the minister may will still be in a black preaching robe looking terribly formal, there is much resistance if you don't wear a suit (I've experienced it, though it's always been in good humour), we have hymns and organs and pews and everything about our form is terriblly formal and traditional.
But go to the congregation where the preacher is in jeans and a T shirt, where there is a jolly informality, or even where there are people with nose-rings and green hair, then the theology, the message is usually conservative, or at least orthodox. The emerging church, for all its radicalism, is still orthodox in its theology (as Ben is at pains to point out).
Is it possible then to be radical in both form and content? Is it possible to have a christology influenced by Marcus Borg and a ecclesiology influenced by Dan Kimball? I hope so, because ultimately that is the kind of church I'd want to belong to. More than that I think its the kind of church that would have the power to become a dynamic religious force in this country. I would hope it would be the church of the future. Yet where is it? Perhaps it is up to me and you (if you agree with me) to create it.
