I don't know of any existing packages which do this... others might have
more to say on this.

In terms of waiting for conditions, you'd probably have to write a wrapper
script of sorts.  To solve 1), you could poll the status of the IPNAT vars
(I'm not in front of _any_ NetBSD box now [sigh], but I seem to remember
there is a way to display outstanding connections which are being
NATed).  To solve 2), you can probably just grab the terminal you logged
in on (tty) and poll until that's free.  The man pages for ipfstat (8) and
ipnat (8) might give you some leads.

There are definitely more [better] ways.  Just my $0.02
