Sorry guys,
Still don't get the point of real time network. For the last 40 years, I have been a planespotter, initially trudging along to my local airport with binoculars, notebook and sandwiches (no anorak!) in order to log aircraft 'personally' seen. The big change for me with the RB (a superb product) is that I no longer have to go to the airport but can log aircraft I have 'personally' seen flying/overflying my local area. With a live network you can track aircraft hundreds/thousands of miles away but, for me, these can't be classed as sightings as obviously you haven't personally seen them. A 5 minute delay network for me is fine as it can provide a good source of reference.
I only need to visit my local airport now if something good has appeared on the RB and a close up picture may be worthwhile.
I stress, of course, that this is just my personal planespotter view.
