Do sasha and kanya share a single AIPS installation or is AIPS installed 
separately on each?

Does kanya have the tape allowed in its AIPS?  Thus a line like the 
following in the $AIPS_ROOT/DA00/TPDEVS.LIST file:

PUBLIC-A   /dev/nst0         Exabyte 8500 (dual density)
PUBLIC-A   /dev/nst1         DAT

When you start AIPS on kanya do multiple TPMON tasks start up?

Can kanya cross-mount your data disk on sasha?  In which case you could 
set up a .dadevs file in your home area and run directly on kanya to 
write your file.  That would be faster and safer.
