  We conjecture that the "nilpotent points" of Calogero-Moser space for
reflection groups are parametrised naturally by the two-sided cells of the
group with unequal parameters. The nilpotent points correspond to blocks of
restricted Cherednik algebras and we describe these blocks in the case G(m,1,n)
and show that in type B our description produces an existing conjectural
description of two-sided cells.
