Actually, that reminds me - and I want to mention it now before I forget about
it yet again - I think that the sudo password input issue might be effectively
handled with the unix pseudo terminal interface (man 7 pty). Ian Piumarta made
a plugin for this along with his really quite amazingly good telnet terminal
emulator.

That stuff, along with other things such as the VNC server, is still available here:

I also recall Ian asking me a long time ago why I didn't add pty support to
the OSProcess plugin, which was a very good question, and I probably should have
paid attention to it.
