Hey,
Of course you can deliver the vedio. All you need to do is hire a 'clever
programmer' who has a very good understanding of how voice/video codecs
works. There are really a few programmers on this planet who are really
aware of how TCP and codecs works together.
It got to be similar to the youtube as it will consume minimum bandwidht
over the t1 or dsl links.
I believe that the DSL links are through internet cloud. Internet is like a
bowl of soup so you definitely have to have youtube like codec application
in place for start.
Secondo, you need to look into enabling multicast for non-DSL links so that
minimum data goes back and fourth to those expensive links.
third, if you've bandwidth related issue, look for deploying WAE-61x
solution for caching the contents. You can push contents from one WAE to
other WAE across to your network during non-peak hour.
