NM already has connectivity checking like dnssec-trigger, which we use
for hotspot detection and twiddle some D-Bus API flags to indicate that
you might be behind a hotspot. GNOME Shell displays a "hotspot" status
in this case. NM will also do split DNS with dnsmasq as a local caching
nameserver to handle the VPN stuff, if your VPN passes down domains or
you specify them manually.
What that doesn't have is the DNSSEC support or the ability to start a
sandboxed web browser for hotspot login before making the upstream
nameservers system-wide, which is where dnssec-trigger and unbound would
