[Red5] Dynamic video quality

The problem is more like: if a client wants to connect to n streams at once,
it quickly consumes over 450kb/s of bandwidth. It also uses a lot of cpu
power, but I really don't care about that :).
So if I'd have static videos, that's easy. I could just have different
qualities as you've mentioned. But, with live streams I cannot do that. So
my question remains ... can red5 downscale quality of the video on the fly?
I've found this, but haven't yet taken the time to look through it ...
but a quick scan tells me, this is not going to answer my question :)
