notes
(update) to get your client-id from Soundcloud: From your home page, select more | developers | my apps.
This looks like the easiest way to play streaming content from Soundcloud over the web, Maybe this example could be adjusted to run in Max.

Example API urls,
this one streams a track: (replace client id with real thing)

This one returns an XML file filled with tracks that can be played:
https://api.soundcloud.com/tracks?client_id=CLIENT-ID
See API reference:
http://developers.soundcloud.com/docs/api/reference#users
(update) Use /resolve to get the user id and user info, given the name – like this:
