i've asked some friends and some are able to stream which confuses me,
and i'm one of them, as reported you in email.
it depends on the client software, at some extent.
anyway, from what i got, you are meaning to "stream" the videos by simply providing the files via http.
i wonder if this method could be consider a compatible method, since most servers rely on additional layers to provide videos, and that's a flash player most of times.
