(ed note:I "unpublished" and then reworked this for tone...)
what if church plants had pastors but used videos of other preachers because:
3. they decided that there are very gifted preachers in the body of Christ and they wanted to learn from those diverse voices as well.
Ahh.. see, now, now you are getting tricky! Using all kinds of good "emergent" sounding words like "diverse"! :)
But again, I think Video Venues actually work in the exact opposite direction of what you are saying here.
It seems as though the Video Venue you have in mind is one where there's a rotation- a community hearing the best taped/broadcast messages from all over, rotating different communicators.
While I'm sure it exists, I've never seen/heard of it. The model we seem to be processing here is one where a single communicator is the one who is (mainly) speaking to the people via the video. (Other pastors may speak, just as in any church, but there's a main teacher).
If I thought videos were a viable long-term solution, your model would be the best. But I have a feeling it's not even on the table. What we're talking about in these satellite campuses, which started as overflow rooms, morphed to overflow buildings and are now complete overflow capuses, sometimes hours away from the main campus, is, in a very real sense, (please excuse the term) franchising.
So, a little thought experiment.
Let's say YourTown Community Church decided to set up a satellite campus an hour and a half from their main campus, showing video of their main guy every week. Now let's say that because of the top quality music and kids programs, YourTown West™ really grew... but it's in a different town, with different kinds of people, people who have heard of YourTown's Teaching Dude, who may even have driven the hour and a half to hear him on special occasions, but don't really have a relationship to him as pastor. And now let's say that YourTown West™ decides that they would like to do a rotation. They are fine with the Dude's teaching and want to keep including him, say every few months, but since there are so many good preaching resources available on video, why not have Bill Hybels speak at YourTown West™ one Sunday, Rick Warren the next, Erwin McManus the next and so forth.
How well would that go over? With the mother church, I mean.
But that thought experiment is more of a tangent than anything...
Here's what I want to see from the church- more pastors/teachers and not less. Video Venues get us less because more and more local churches will be feeding on steady diet of communication from elsewhere rather than developing the teachers among them. Where does a man or woman who feels called to preach get practical experience if their local church is a video venue?
Your question, "they decided that there are very gifted preachers in the body of Christ and they wanted to learn from those diverse voices as well" is the exact reason why Video Venues are a bad idea, I think.
