How can you change the node description OTA

[doug]

I am setting up nodes but having trouble identifying them as they all end up with the same description its because I'm a bit lazy and don't like having to change my sketch for each new node I make.

When I load a sketch if I want a different description I have to put it into the sketch and would really like to be able to set it afterwards using some sort of C_SET message.

Currently I set this in code as below

present(RTCSENSOR, S_INFO, RTCSENSOR_DESCRIPTION, false);

Does anybody have any idea where I would start. I guess i would use

void receive(const MyMessage &message)

However once my node has received the data how do I use it to update the node description?

Any suggestions or pointers on where to start would be appreciated.
