Always I have paid attention to NXT,I hope to heard more good news of it.
I can now reveal a couple of details.
1) The server and client writes on server node.js
http://en.wikipedia.org/wiki/Nodejs 2) Modularity - you can easily connect modules and build capacity
3) Design the client will be in a separate directory will be easy to make your own templates
4) Everyone will be able to participate in development NXTL (will not have problems with both the NXT, where everything depends on a couple of developers)
