I also considered installing MOSIX for some time, and avoided and
postponed it for several reasons, but recently I learned something which
made me stop considering it altogether.

In the advanced OS course in HaifaU Oleg Goldshmidt showed benchmark
results, which show that migration does not enlarge the ability of the
cluster to deal with loads in a significant manner. Back filling, on the
other hand, does.

So there is no point in working with a modified OS, where you are not free
to update to a kernel of your choice, because you are using a huge patch.
