it turns out i had a bit of extra time since it's too icy to leave the
house. :-(
anyway, here are all the programs that take -x mntpt, as determined by
the man pages.
vnc(1) vncs
httpfile(4)
6in4(8)
ndb(8) ndb/cs, csquery, dns, dnstcp, dnsquery, dnsdebug
ppp(8) ip/ppp, pppoe, pptp, pptpd
secstore(8) secstored
syslogd(8)
udpecho(8)
none of these programs take a dial string.
however, some of them could (see nettest(8),
http://sources.9atom.org/magic/man2html/8/nettest)
such as syslogd, udpecho, secstored and vncs.
httpfile, well, rob has already made the point.
