That, I don't know. At the time the old I/O 0.8 was implemented, GTK and
QT were not the `standards' they are nowadays. The (new) Object I/O only
works on Windows and MacOS, there was never a port to Xview.

Yes, some people have worked on a GTK version of Object I/O. I don't
know the details nor the status of the project.

Yes, one could separate the low-level TCP/IP bindings from the Object
I/O stuff. I did that once and used it on both Windows and Linux. All
platform specifics are in a single small C file (sockets are almost
platform independent). The code is currently not in a
polished-ready-for-release-as-a-library form, but I'll try to make it
available this week. Especially the error handling is non-existing, but
it might be a start, please improve it.
