Any developers considering building a tracking type plunging with the ability to send a message or form or anything else that could be sent. eg. we can track people who are registered to our app like friend or child or anyone else. when we tap on their location on the map and it tells us who it is with a button to click to send them whatever it is we have set our app up to do? eg. if its a family member then we could set up our form to be a simple message to tell them to pick something up from shop or if its your child we could send them a message to come home etc. and the receiving party is prompted to accept or decline. if they accept then their marker or icon changes colors so you can track that person or prevent re sending same message etc. it could be applied to many personal and business uses. I realize this would be a complex set up but could be charged higher purchase fee/monthly fees etc to make it worth putting together Just a suggestion for this powerfull tool buzztouch is. It seems nothing is impossible here.

Sounds a little like text messages. Not sure what the difference between that (SMS or FB messages) and this idea is. However it does sound very intriguing...

that was just simple example. could be used to contact field staff closest to a business appointment and get instant confirmation or create a personal app for fleet management etc. sky's the limit with possible uses.

Have you looked at scringo? Ive got some features like that running on my app but you could further customise it..
