[44net] NOS "versions"

Does such exist.... Has anyone created..... can said code be easily separated / compiled separately..... What I'm looking for is a "version" of nos that is devoid of any of it's networking functionality or well at least the bottom 3 layers of the OSI stack. The issue being that NOS has long been a standard and familiar interface for networked amateur radio BBS systems. I'm good with that. over the last 20+ years though we have moved to computers and operating systems that are much more capable, especially when it comes to processing speed, memory, and a decent built in network stack. I now no longer need my application (BBS) to handle the network layer stuff but simply need what amounts to a good BBS interface. can/has this functionality be/been gutted/separated out from the NOS code base such that I can end up with an application that simply is setup to listen on the proper port via init.d and present *ONLY* the familiar bbs interface while the OS handles all the networking stuff and the application not even being capable of such.
