Interesting as all this may be, phoneguy610 has illustrated the basic point here. There isn't enough bandwidth - yet, and at reasonable cost to most consumers. There's the battle of the future, bandwidth. Once you deliver that reliably, the apps will follow. So far, this is not the case. Maybe in some pockets, but on average - not even close.
What will be the shape of phone systems in the future? This is anyone's guess. The counter argument will most probably be concerned with security and access to tracking information (for advertising, of course!). How would you like to be "chipped", only to have "approved" advertising sent right to your brain? A hosted "solution" (to what is it a solution?) is in fact only software that appliances talk to. The track record for most software is abysmal when it comes to quality metrics. I suspect that this "product" is merely a bold push to sell communication as a service. Since there is very little outlay beyond licensing fees (tell us developers, just how much markup is there in here? I know it must be massive) leading to obscene profits. The sharing with some low morals type dealers provides the market push they need to create market traction. Coupled with slightly lower buy in cost for the client (leveraging the something for nothing gene in consumers) is hoped to provide the final momentum to falsely create the image of reliability to complete the total illusion.
If there is anyone here who doubts what kinds of profits are generated by writing software, just have a gander at Micro$oft and other similar companies. I'll bet the the actual expenditure for their operating systems is concentrated in anti-theft of software. What is being sold is essentially ... nothing. One copy they decide to release, and the packaging/advertising is really the bulk of their production costs. Now, how could this become even more profitable? Hell, no packaging or media at all! How? Hosted communications solutions. Man, I hate that phrase, "hosted solution", as if it's good for anyone. How about the theft issue? Software as a service where the actual code is no longer valuable, but the license to operate it is. Once you consider these things in those terms, you have a better understanding of the central issues here.
Smoke, mirrors, vapour-ware. I'm not buying into this at all. Besides, massive amounts of bandwidth available for simply cracking the common software code ... now that is worth some effort for some folks. This is probably a lot of fun as well. It doesn't take much to gain access to a large body of running common code, and even less to deny service by crashing the works. Probably even more fun. Remember all the trouble windows users suffer through.
