With the advance of Smart Phone technology, the usage of a phone is not anymore limited to calling only. An application tier has been added and with applications come options, configurations, steps, setup etc..
I was on the phone the other day with a friend who needed help configuring an Application in his Blackberry, it was very difficult to explain the steps over the phone. So an idea popped up, if implemented it would add an edge to the Mobile technology, its Sharing Mobile Screen.
If I could allow sharing my mobile screen while calling someone so the other party stream my phone screen to his mobile, It would be easier to show my friend this while he follows the steps instantly in his mobile.
Morever, for demo purposes in a conference call one can share his mobile screen to present a certain mobile application to the group.
Since mobile screens are relativly small, compression will get better and thus the stream would be sent faster. Yet, this idea has its challenges and limitation, lets brainstorm them.
