     I'm afraid I would have to come down on the side of opposing such an
option.  When an ISP is incompetent to provide a properly functioning
connection, which is, after all, part of what it is being *paid to do*, the
better solution is to fire the ISP and hire one that *is* competent.  The
delay that I had in following that advice was due to the combination of a) my
mistake in having signed a one-year contract with an early termination penalty
and b) severe poverty that made suffering the penalty infeasible.  I still
question whether I was right or wrong in offering relay service that was so
fucked up without any way to advise clients of the hazards involved in plotting
a circuit through my relay during that time.
     FWIW, I am currently dealing with a new (to me) situation involving my
current ISP, but I'll post comments on that later.
