Unfortunately, XMPP wasn't popular in researchers and companies, but now many people are being interested in real time local communications, especially, in Japan, 3.11 earthquake arise some issues as follows... --- 1) Current network centric server / client system didn't work during a national emergency. So a local independent network like a city level is necessary. In the daily use, these network will connect the Internet, and will be useful for citizens's daily life. But in the emergency, these local network will be work independently when the link to the Internet is cut. Current "Server Client Model" is tend to centralize functions in big "Data Center", but in small local network like a city level can't utilize such a big data center. So we needs more light weight service architecture like a p2p model. I think XMPP Architecture will resolve this issue, because XMPP server, or system doesn't need enormous functions in server side. 2) Current "Web Services" in the Internet are not sufficient, in many case, web services are lack of functions of realtime information exchange. For example, Twitter provides realtime message exchange functions, but to utilize Twitter service, Twitter needs big real time database at back end. And essentially "Web Architecture" is lack of paging function, or server can't initiate communication path to any client devices. I think XMPP is very useful for direct communications between peoples, or between man and machine/sensor, even in a national emergency. --- As a result, I think XMPP has many chances to become popular in next few years, and XMPP is key technology to utilize local realtime communications.
