Cheers Mike,

Yes, MQTT is really cool and quite simple.

When I was working I did look at SOAP and XMLPRC as possible ways of shifting data between systems for account provisioning purposes, but never implemented anything. MQTT might well have been able to do what we wanted.

It'd be interesting if you could tell us more about the sort of applications you have in mind for it.

It's always cheering to find the comment notification light on when I get up, so go right ahead :-)
