Chris and Mike and any other SF Bay Area residents here are very welcome to join us on the 20th.

Thanks greg. Sorry I wasn't clear. We currently don't have any connection and I need to know what kind of bandwidth we need to stream the video from NY.

It's in the works but I don't want to get more bandwidth than we need because it costs more.

Just a standard 1.5M DSL line or a cable modem connection should work just fine.

thank you! that's what I needed.
