Evolution of shells in Linux (developerWorks)

I don't think there are many willing to step up and fix readline, after patching every mainstream VT100 emulator out there. The paradigm of redirecting debugging information, output and input echo to a single character stream is plain outdated.

Does anyone own any of the TeleTypes that might brake if anything is changed? I, for one, have never seen one, and call for a rewrite. Keep stdin, stdout and stderr - but throw out the overmultiplexing and terminal emulation.
