Yes and no.  The programmer itself is almost, but not quite, as 
blindingly simple as you can get -- parallel port -> hex buffer ->
PIC chip.  So assuming that most PIC chips program with a 13V Vpp,
5V Vdd, and some fiddling with PGD and PGC, it's just a matter of
software at that point.

I wrote my own programming software based on the Microchip datasheets
which runs under BSD.  So if I did that correctly, it should be 
compatible with my chips.  I also used PICALL for Windows as a 
test when the first didn't work for the 16F870.  It's supposed to
do that one at least, so there's probably something in the timing
of the programming cycle (or something) which both my homebuilt
(and admittedly naive) code, and the third-party (but now unsupported)
program, are missing.

That's my assumption as well, but I thought it was an odd coincidence
that the parts which did and didn't work happened to be from separate
sample shipments.  So I thought it was at least worth asking.
