I’ve written a very simple osc server which shuttles messages between chuck and a browser (only tested via Firefox so your milage may vary).  I’ve written helper classes for chuck that make it easy to make a parameter modifiable remotely. The browser connects to the server via socket.io and the chuck instance uses UDP to talk to the server via osc.  The server is written in node.js.
