Doesn't Communications Controller for Linux (CCL) still support SDLC and SNA on the pipe?
In practical terms, I'm confident that most SNA traffic these days is TN3270. Is anybody still using APPC? -- Shmuel (Seymour J.)

They might as well drop JCL or TSO. Anything that talks to a 3270 (except local non-SNA channel-attached) is using SNA. What they could do is to write a purely TCP version of TCAS, and slide it in the same way TSO/VTAM existed in parallel with TSO TCAM 40-ish years ago. But this would still have a bunch of the SNA attributes to it. What has for all practical purposes already been dropped is "SNA on the wire". There are no more Front End Processors (3705 and descendants) , and I haven't seen an actual LAN Channel Station (LCS) or even an emulation of one for many years. I think the newer (OSA) interfaces till support SNA, but is anyone using them that way? So how does SNA traffic get onto a network in the modern world? I think the only practical answer is encapsulating it in IP traffic, and I think that means Enterprise Extender and such. In any case, there's nothing wrong with writing SNA programs for fun. The OP said nothing about marketing it.
