[aprssig] APRS Message Idea

[Robert Bruninga]

Yes, but that is a two step process.  The way I read this
UIview add-on, you send the message the normal way
and when it times out, and you want to then send it
via store and forward, you ave to send it again to the
S&F node.  Not at all seamless to the original send-and-
forget design...

UIVIEW anyway.
