I would be interested to hear your opinion on how tcp over multicast would
work.

But I agree with your general point that it's a bit much to expect an
application to work where it depends on intercontinental multicast to work
flawlessly and where the upper levels of the application don't even
tolerate out of order packets.  "Be liberal in what you expect.  Be
conservative in what you send".
