The ability to print multiple fields can be done now using a method published by Mikal Hart here: http://www.arduino.cc/playground/Main/StreamingOutput
Its syntax is a C++ standard but I wonder if it looks a little scary to non-technical people?
Took a look at that link. I'm not exactly non-technical but I have no idea what the relevant line (below) is doing.
Does this compile as is? class T?
template<class T> inline Print &operator <<(Print &obj, T arg) { obj.print(arg); return obj; }
