Absolutely - though these types of solutions are generally out of the reach of the average publisher. Even in that case, the server would (probably) want information about dropped frames from the client. > So, to generalise this, I agree there should be a solution such as what > Chris Double is suggesting with an additional resource describing what files > can be switched between and then JavaScript doing the switching.

We do this currently with SMIL files, which have all the necessary information. In that case the only thing I could imagine be necessary is some sort of flag to indicate that the file listed as the src isn't the actual file to be played, but rather a list of resources.
