Indeed it is. We have an application that just do that. We have several 
sockets opened to control several daemons running in an Ethernut from a 
applet GUI loaded from the http server of the Ethernut, while the 
Ethernut sends data to the GUI in real time for monitoring purposes.

In our application the server is in Ethernut and the client is in the 
applet, but there should not be any problem doing it the other way 
around, if that is what you want.

Just use normal socket programming to develop client and server, that's 
the beauty of NutOS here. Then place the applet in the root of the 
Ethernut http server and download the applet with your browser. You 
might need to sign the applet.

I think I have an example of a "kind of oscilloscope" that I sent long 
time ago to to a member of this list. The problem is that the files are 
binaries (for Ethernut 2), and I don't have the source code any more (I 
just rescued the binaries from my mail files).

For more details check

If you still want me to send you the binaries let me know. They might 
not be good for learning, but might demonstrate what you want.
