Hi Sajjadkhan.  You're right, there is a huge opportunity in this area.  The fact that there are several solutions from different developers currently being worked on shows just how in demand this tech is.  We think that we will be able to carve a niche out.  We are always open to suggestions from the community for features and to tell us what works and what doesn't.  I think this feedback loop development is one of the many things that will set us apart from our competitors.
