I have two suggestions, though: It seems's bandwith is quite 
limited, at home (where usually I have no problems watching streamed 
video) it stopped several times due to the buffer running low and I had to 
wait about a minute to restart. Now I am in the office (with a 100MBit 
uplink more or less directly attached to the German backbone) and it does 
not start at all (spinning dots of death).

Maybe you should consider uploading it to as well? It's free 
(i.e. no money, no ads) and also hosting CC licensed stuff.

You only notice in the cuts where it drops to silence for a second or two. 
Maybe you want to add a 'comfort noise' track?
