Vishal,
I can say that this is not the correct place for this.
You may want to contact the sales team, they have a lot more information than we would as support engineers.
On the plus side there have been many products that were developed external to CA, the first one that I am aware of is option pack one, it was later bought and added into our product as policy express. The latest that I have heard of is CA sigma, basically a TEWS client that merges IM and GM more seamlessly.
Good luck with your development.
Bill
