By needing the emblend to be done all in one shot like this you loose
the advantage of make here.  Especially since if you stop the job at
this point, you have to start the emblend all over again.
Distributing the other pieces is a small job in comparison to the
emblend which seems to take the most time.

So it seems that emblend is keeping the entire image in memory.  What
if you broke up the job of emblend so that it output it's pieces to
intermediate tiles files which were then assembled into the final tiff
after?  Then maybe you could distribute the non-overlapping tiles and
and input images to another machine.  You kind of "lock" those tiles
until that section is done.  The idea is to keep in memory just the
section you are working on, even it it's like 100meg or so, that's not
too large.

Unless you do something like this, I can't see how hugin is going to
be able to create a pano any greater than the available swap space.
How difficult would it be to rework emblend to do something like the
above?
