Re: standards exist from ITU, GSM and IETF
XMPP didn’t catch on because it was even worse than the SIP it was trying I replace.
I have to implement an XMPP server soon. I have been googling like mad for months and while I’ve implemented dozens of major protocols in my life, I haven’t the slightest idea where to start with XMPP.
If you can’t implement a protocol, you can’t integrate it. It looks to me like XMPP will take months or more just to get the basic features running.
No I can’t use a library. They’re not good enough.
No I won’t use a C or C++ program, I refuse to take those security risks. I will need to support communication between 100,000+ devices and the only reason we need XMPP is because of security. I’m not going to start by using languages which run native code on the servers.
