What matters is that you can, which means someone you know or trust can and give you access. These days it's much, much easier to run simple services like messaging if you consider the proliferation of remote accessible NAS boxes and such in households. Adding a messaging service to that is easy. Other than that you can use Sandstorm too if you don't want to operate a server. > Things like WhatsApp or GChat do not simply replace XML with JSON I'm sorry you thought I said WhatsApp or GChat use JSON. I mentioned it in reference to other messaging services.
