 Description

-An VNC client implemented using HTML5, specifically Canvas and Web Sockets.
+An VNC client implemented using HTML5, specifically Canvas and
+WebSocket.
 
+For browsers that do not have builtin WebSocket support, the project
+includes web-socket-js, a WebSocket emulator using Adobe Flash
+(http://github.com/gimite/web-socket-js).
 
 
 Requirements
 ------------
 
-* A browser that supports Web Sockets (mostly Chrome as of Apr 6, 2010) 
-  and Canvas (most browsers)
+Until there is VNC server support for WebSocket connections, you need
+to use a WebSocket to TCP socket proxy. There is a python proxy
+included ('wsproxy').
 
-* Until VNC server support web sockets, you need to use a Web Sockets to
-  normal socket proxy. There are a couple reasons for this:
+There a few reasons why a proxy is required:
 
-  1. Web Sockets is not a pure socket protocol. There is an initial HTTP
-     like handshake to allow easy hand-off by web servers and allow some
-     origin policy exchange. Also, each Web Sockets frame begins with
-     0 ('\x00') and ends with 255 ('\xff').

   2. Javascript itself does not have the ability to handle pure byte

-     them with Web Sockets. The python proxy base64 encodes the data so
-     that the Javascript client can base64 decode the data into an array.

+  3. When using the web-socket-js as a fallback, WebSocket 'onmessage'
+     events may arrive out of order. In order to compensate for this
+     the client asks the proxy (using the initial query string) to add
+     sequence numbers to each packet.
