Security/privacy is a fleeting expectation. Cloud services and open source have put demands on our privacy and security that are (a) under valued (b) over exposed.
- most email interchange between server is router directed but in the clear
- most VOIP is not encrypted at all and uses UDP for media transmission
- DNS services tell the providers what you're reading, watching or listening to
- Search providers know what you're looking for
- TOR may or may not be secure but someone could unwind your privacy if they can connect the entry and exit from the TOR
- SMS messages are stored on the telco servers
- every time your cell or sleep computer wakes up momentarily to see if there is something for it to do pings whatever wifi it sees reporting your MAC address to the provider
- your smartphone GPS and smart maps tell the provider where you are and what wifi SSIDs are close by. It also reports your speed that can be correlated to it's maps for marking congestion however it also knows your speed and at some point it might call the cops on you.
So when your company is 50% iOS/OSX and 50% ChromeOS/Android and whatever else is out there... how are we to standardize so that we can all talk to each other. The security issue has to go away and vendors have to get the interop working. There is no reason why facetime cannot talk to hangout! Granted WebRTC is part the way to creating an interchange and with open source PBX' like Asterisk, FreeSwitch and others it has to be possible... and sooner than later.
One huge challenge is that when you or I are in the DMZ of this communication war you either have to pick sides or use them all. "All" is just not practical. And bringing this in-house is not practical because the cost of development, maintenance, integration is not possible unless you have the deepest pockets.
I'm not sure if I made the case I was hoping for but I am frustrated and at the end of this rope.
