Pls go there an update ur project details..... Also remember to put a two sentence discription in the main page also.....

Hi Mark;
My gut feeling is you that should go ahead with what ever the easiest
format! This is not something that has tried much ... and I am eagerly
waiting to see this thingy working:)
Thanks
