Informix Client/Server products on unsupported network

Hi, I need to implement Informix client/server products such as 4GL for Windows in the following environment: Token Ring network with several OS/2 Servers running IBM LAN Server, 1 SCO Unix Server running TCP/IP, truckloads of PCs running IBM LAN Support Program and Frontier Technologies SuperTCP for Windows. As I understand it, Informix only supports a limited number of network protocols such as PC-NFS Ver 3.5, PC/TCP Ver 2.5, Wollongong Pathway Access, AT&T StarGROUP Ver 3.4 and Novell IPX/SPX. Unfortunately the TCP/IP environment is fixed as it would cost a fortune to replace it on over 1000 PCs, and the available base RAM on the PCs is very limited - SuperTCP only uses 13K of base RAM & does the rest in DLLs. So...Is there any way of tricking Informix-NET PC into working with SuperTCP, or perhaps is there some other product that could replace the Informix-NET PC part of this equation? Thanks in advance.
