The last time I played with Real's SureStream[tm], it created the
various bitrates at encoding time and embedded them all in one big file.
Realserver then picked the appropriate stream from that huge file and
sent it to the client. That's been a few years since I tried that,
however, I doubt they changed that to "real peeling" since.
