In all of the (2) FAQs and tutorials I have read, they say that programming IPX is slightly different to TCP/IP, but they don''t say how. How?

Using DirectPlay:

Instead of creating a session using a TCP information block(forgot the term, trying hard to forget anything I ever learned about DPlay) You would specify IPX as the provider instead of TCP/IP

Using Winsock:

When creating a socket, you would do everything the same, but instead of using IPPROTO_TCP or IPPROTO_TCP and AF_INET, You would use the definitions for IPX/SPX. Keep in mind that IPX/SPX behave differently than TCP or UDP. They are stream sockets that preserve message boundaries.

Hope that helps,
