MobiSite - A mobile held Web Site

The world is full of information exchange. With the advent of web, businesses have got a wider reach. Just log into a website and search for what you want and go to your service provider website and get what you want.
I have a shorter version of it. Iam a service provider say a Doctor. I am ready for a service with in 50 miles of a region. The whole way of reaching me through the website or yellow pages search is not that coool. So what I want to say is all service providers should have some thing like a MobiSite. This is a tiny webservice concept in my mobile phone that is throwing the information related to my service on air. If a client wants a service take a mobile or a PDA and search for what service he/she wants with in that region. Bingo!! you have the list of people who have been throwing their information in that region.

Well this is the coolest technology I think we will see in future. The whole idea seems to be very very sexy.
