Yet another (IMHO "elegant") solution is to take advantage of the fact that
pathalias utilises data IN THE ORDER IT FINDS IT with respect to multiple
entries. So, for example, if there was a link between my machine at home
(pallio) and system blurf on the west coast (lakart & pallio are in Boston)
that I want to be able to use from lakart and pallio, but I dont want anyone
else to know about I do the following: create a u.PALLIO file with the
following two lines:

pallio	blurf(HOURLY)
blurf	pallio(HOURLY)

Now when I run pathalias (every night :-) ) I invoke it as follows:

pathalias u.[A-Z]* [ud].*

which causes the u.PALLIO (and u.LAKART - we have one) information to be
read first, hence it takes precedence over real information. I think this may
well do what you want.
