Hi Sameer,
We are working on such a system under our Radix Solution platform. There are some interesting open source projects in this area - ThinStation, NetStation, DietPC, PXES and some more.
ThinStation (http://thinstation.sourceforge.net) is the one we liked the most. You might want to try that out.
We can also look into collaboration possibilities if you are interested. Let me know.
