functionality similar to GNU screen and general purpose io piping and Hubs
Provides the iosrv server, ioshell client, and io wrapper script. General usage is via the io SRVNAME command which functions bimodally to start the client or server as needed. Additional shells can be created on both the remote and local machines and shared to other iosrv clients. Remote #, local #, attach # commands are used once connected, with # always being a multiple of 3. Each new rc shell uses 3 i/o Hubs, one for each of the standard file descriptors.
