exactly, use g_spawn_async_with_pipes but allow it to accept env vars
for the path of the executable it calls, that way you can create a
snapcraft.yaml that pulls in iptables and your command will just do the
right thing if $SNAP is set (i.e. iptables in your snap might live in
$SNAP/usr/sbin/ while on a deb system it is just /usr/sbin, this also
gives you full control over the iptables version in snappy)

yes, please start by filing it under the snappy umbrella [1] project
and we'll add the necessary bug tasks for all bits and pieces involved
then.
