Point taken. It is because I wanted to start with something small and specific and expand it in the future. So, I did not really describe the big picture - the overall vision, future work, that sort of thing. In retrospect, may be, I should have done that. I will take all of the input I have received so far and all of the responses I have given, refine the definition of trampfd and send it out. Please review that and let me know if anything is still missing from the definition. Thanks. Madhavan
