Crease converting

Hay IStonia,
The most question I hear about NVil is - IS it possible to safe creases in obj?

I just thought may it is possible to make some algorithm that will convert creases to support edges(Like hard edges in Chamfer)? Taking in account crease weights?

would be nice!   I often take my models into Maya for final output....but there is no way to export crease Data.

FBX would support crease data though.

OBJ doesn't support subdivision creases.
I once made a suggestion to implement some routines to export them to a TXT file (like CSV, XML or some other) so they can be processed by scripts (in Maya, Houdini, etc.). This would work.
