From my tests, it does seem to work.  The only hitch is that you cannot  
restore those files on a Sun using SunOS restore command.  You must use  
rrestore from a NeXT.  restore on the Sun core dumps when it tries to read  
that dump block!
We currently have one tape that has several dumps on it in succession: 2  
Sun dumps, and 2 NeXT dumps.  Restores off of both of them seem to work  
OK.

BTW, there is another thing that tripped me up - you must specify a  
filesystem on the dump command line with NeXTs, while you can actually  
specify any directory with SunOS dump.  Not giving an actual partition  
name (/export, or /, for instance) results in the wonderful bad sblock  
magic number message.
