Is it possible to communicate between two droids? For instance, it would be nice to have an application which can communicate with another droid and invoke a short pop-up "hello". Imagine a situation, you are sitting in a subway train, and u see this nice beautiful lady sitting across at the corner. You surely do not have a way to muster to walk up and say hi, but u surely can ping her cell with navigational/directional IM which will buzz her a "hi ... this is the red shirt guy sitting across......" and if she seems interested in u, she can respond or ignore.
Is it in the relams of do-able technology yet? Is an application development possible in this area? I see a lot of use in such short range area, whereby u need not know the other persons tel number, but if his/her droid comes in some cognizant radius of ur droid range, then u can IM/buzz to say a few very short messages... and yet decide to remain strangers or make friends.
If droid can do this, this will be a very UNIQUE offering to the telephone world, not yet available. This will be like everyday event talking to strangers on the roadside... when u ask a stranger for some thing/direction/time/wishes... and since most of the world is filled with strangers than friends... it is one other reason this technology will bridge the gap further!
