[aprssig] NetNodes, the future

This NETgate idea is another way to set up an Igate? An Igate is an
internet gate. Or is this an autmatic system that you connect to with a
direct entry of one call sign? I am getting so confused with the "fixes"
and am not absorbing them readily. I am sorry about that. I'm in an area
that doesn't have enough coverage and am wanting to set up more RF digis. I
am not in a situation that many are where there are too many digis or too
many operators. There is one digi SE of me and a low profile digi in my
county but none N, NE, W or SW in bordering counties. There was one west of
me but disappeared about a year ago.
HELP.
