Can Flash/Actionscript Upload to a Different Server?

Question

Is it possible to upload a file to another server or pass a file from a Flash object to a script that resides on a different server?

I would like to upload a video to viddler using their REST API. I wish to upload a video directly to them. Is Flash capable of this?

If this is possible, I would appreciate links to tutorials or existing code I can use to make this.

Thanks all

The Flash runtime is capable of this, at least Player 9 and later with AS3. However, the big roadblock is security. The server must export an XML file crossdomain.xml which will be read by the player, and its contents determine whether a request succeeds. See here for more information.
