Running the demon as a seperate thread is a good idea, I had not thought 
of that, I was going to 'demon.py &' it - which must be pretty inefficient.

Queueing the data, like a FIFO buffer, that negates the need for  
/data/data_flag, if its read, its gone - thats elegent -  I like that 
:-) . I could write a script that implements a FIFO function - or maybe 
I will find one in the vaults.

As to using a socket, I have only encounterd passing references to them 
mainly when tweeking the linux kernel , Can you point me in the 
direction of how you can use them in Python ... ?
