It sort of blew my mind, last night, when I realized that this is essentially using websockets like FTP because you can transmit any document, from any computer with a network to connection, to any other computer with a network connection, no matter how large or complex. Just have to break it into chunks, with a predefined order, with 30040s (or as a static linked list, but that'd be a different app).
And we have it running. Pretty cool.
