WRT hip wrangling - Wouldn't it be easier to use hexpand to explode the 
hip into a hierarchy of ascii files, and work on them in that state, and 
then hcollapse the wrangled files back into a hip file?

Just glancing at it, it appears that locked SOps save their data in 
.data files, which are just .bgeo files. You could do whatever parsing 
and manipulation you needed to on locked data by converting the data to 
a .geo file (using gconvert) , munging the resulting ascii format file, 
gconverting back, and hcollapsing it all back into a hip.

Seems easier than hacking a raw hip file - or did I miss your intent?

BTW, are hip files still straight cpio? Anyone know?
