Since so many people have asked, I've written up a description
of what you have to go through in order to do a webcast legally.
It's a long document, because the laws about such things are a
confusing mess. If you notice any factual errors, or things that
could be clearer, please let me know.  We have a rental scissor-
lift: one of those golf-cart-with-an- elevator-on-top dealies.
It's great fun to ride up and down.  The bathroom walls are
framed out now, and the in-wall plumbing for the fixtures is
just about done. There's one group busily stripping all the
unused conduit off of the balcony and support beams, and another
group following behind them painting it all black. We may end up
doing something more intersting with the major wall surfaces,
but the beams will be black. Once there's a fresh coat of paint
down, the electricians will start running the new conduit, and
the plumbers will run the new water lines. Usually conduit and
pipes go in before you paint, because most people don't want to
see that stuff
