It does not need to be a turned into an object. The idea is very old  
going back at least 10 years to a DCC presentation by John Hansen  
W2FS. I forget what he called his idea, but it periodically  
resurfaces. Never been well implemented though. If you want some piece  
of info, you ask and it is returned in a message. Easy.

There is no configuration needed for the IGate, the message from the  
data server to you is automatically gated to RF.

This is a good way to do it, it takes zero bandwidth except when it is  
being used. It will work everywhere that has a two way IGate. Easy.
