Sharing data might be easy depending on what Unix it is and what's installed. 
Keep in mind that the AS/400 supports NFS and that even DRDA is possible (if 
the Unix side has the necessary components.)

An iSeries at V4R5 has multiple Unix-related options. QShell is a Unix-style 
shell for running scripts and utilities. Hundreds of Unix APIs are native, 
available even to RPG. Linux can run in a LPAR (I know -- already 
disqualified.) And PASE provides a binary-compatibility with AIX. There are 
some Unixes that don't provide as much.

PASE is an intriguing possibility. It's essentially nothing more than some 
run-time libraries (costing maybe $100 for V4R5?) that provides an ABI for AIX 
executables. I've compiled a C program on AIX, FTP'd it to the IFS and run the 
program with no problem. (Of course, I also tested modifying the resulting 
streamfile object with EDTF to see what would happen and it ran just as well. 
That was one difference between those and native *PGM objects that made me 
nervous.) I'd expected somebody else to mention PASE by now, but QShell and 
Linux were all that showed up.
