this is exactly what I need. I don't bother for the length, as I know in 
advance what is that file...
this is a great feature : your streams can be delayed for any duration...
(I plan to have daily dumps, so you can have from 24h to a few sec delay)

Otherwise, without range, I'll have to feed the dump into icecast as a 
stream with an ices playlist (this worked, but then your're limited to a 
particular delay: if your start ices 1hour after begining the dump, 
you'll have 1h delay. For multiple delays, you need multiple ices 
instances. Too much.).

I'll try and tell you the results on the list.
