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.
