I would like to skip the serial stuff and use i2c / DDE as well, but
the OOPics will be separated from each other by some distance and
everything I've read is that i2c should only / can only be used for
very short distances.

I'll plan on getting the level shifter for the S board, and getting
each to talk to the PC first.

I'm hoping that at RS232 levels I can get the distance I need. If
not, I was planning to look into RS232<->RS485 converters (Wikipedia
says RS485 can go 4000ft!), or using something like a Prizm MicroMux
(http://www.prizminc.com/pdf/DS_micromux1.20.2004.pdf) to convert
RS232/RS485<->Fiber between the cards. (I suspect those fiber modems
are pricy though!)

Ah, but I'm getting ahead of myself. First, I'll try to get the
serial basics down and order the MAX232 for the S card.

Thanks for the help. I'll keep the group posted if I can get any of
this "long distance" serial stuff working.
