There are implementations which approximate bittorrent written entirely in javascript. It's possible.

However, I really doubt infrastructure costs dominate SoundCloud's money problems. Significant, yes. But a major engineering overhaul developing an entirely different architecture for distribution which might either not work or alienate customers is probably not an appropriate move when in that situation.

Maybe it could be something to do as a clean shut-down to help things live on (an amazing thing when dying companies do things like this to end well) but not ... expected.
