Hmm ...

Talking off the top of my head, I think that it would not be too difficult 
to come up with a VMS program that reads files from an ULTRIX partition.  

I'd start from the source code for ULTRIXes standalone libraries (the ones
that are used by the boot program and so on).  These have the capability to
follow a pathname from a partition's root directory, and read a file.  All
this stuff is written in C.  It would be necessary to replace the calls into
the standalone disc device driver with the appropriate VMS stuff to read
blocks from the ULTRIX partition, but that shouldn't be much of a problem.
[You might find that the standalone libraries do not understand ULTRIX
symbolic links ... but that is no great loss, and it should be easy to
implement if you need the facility].  Obviously I'm assuming that you have a
VMS C compiler and legitimate access to the ULTRIX source code!

Reading a VMS from ULTRIX would be much much harder.  For a start, the VMS
filesystem code is not written in any language that ULTRIX understands ...

Disclaimer:  
   Like I said at the beginning, I'm talking off the top of my head.
   If you believe me, thats your problem not mine!
