I once did something similar to control a rack full of Opto-22 
sensor/output modules. I used an ethernet-connected RS-485 controller 
(NEMA 4X-rated -- if I'm remembering correctly, it was made by Black 
Box), and a NEMA 4X-rated ethernet -> 802.11b bridge box.  The module 
holders were daisy chained off each other with RS-485.

Peace...  Sridhar
