Bandwidth Notation

I was reading through your spec and found it echoes a lot of my thoughts about the benefits of a purely JSON manifest and One Right Way and noticed this part:

Should bandwidth be declared in kbps rather than bps? I'm so bored of typing extra 000.
Or should it be a more complex type, where "1000k", 1000000 and "1m" are all the same thing? Oh no wait, one way to do it, right.

Why not perhaps exponential notation like 1e6 which can quickly be serialized without any special parsing

Support WebM

Force explicit declaration of SASH variant

IE: time based, segement number based, SIDIX/byte range based.

Needs time-based profile support!

Great idea, but this needs time-based profile support!
Perhaps something like this, with times forced to be contiguous and in milliseconds?
