The point being that if you implement an IPX server, presumably you will need to implement reponses to GetNearestServer(). If you implement it on top of an existing IPX (like yours), then you will need to use an ioctl() to retrieve the information to respond via proxy (unless you illegally copy login.exe from a real Novell server). All I'm saying is that your IPX implementation is sufficient (you claimed that it wasn't usable as a general kernel extension because it wasn't appropriate for thistype of use). The SPX note was for connectionful services. Like X. SPX also requires a working IPX, and SPX service advertisement is via SAPping by port.
