Brian Toby might be the best person to contact over this as he
is the chair of the IUCr COMCIFS Powder Diffraction Dictionary 
Maintenance Group

Rietica Rietveld by Brett Hunter will import CIF files (from the Model Phases
menu):
 
  http://www.rietica.org

=====================

MAUD for Java by Luca Lutterotti is also based around reading and writing CIF

>From the MAUD Help:

"The program may import crystal structures from the ICSD 
database, by exporting CIF formatted structures from it.
Maud databases and analysis files are ASCII files in CIF format (enriched
by additional terms I never found in the CIF dictionary) and can be
edited manually."

Others?
