There's more to it than I originally let on. We have 20+ PLCs on 5 different A-B highways, some bridged to others with various A-B devices. A single DF1-capable FBM224 would probably have trouble with it, though we could use one per A-B highway and probably get by. As it stands, RSLinx as an OPC server handles our setup effortlessly, and though I don't love the Windows aspect of the AW70, it has worked pretty well once we got off NT. That said, I got my first exposure to Prosoft a couple weeks ago. Interesting little box. Probably the way to go for Modbus with Controllogix/Compactlogix, as A-B's own implementation is in ladder (?!) and it doesn't seem very robust.
