The thing that gets me, though is that the language used is so general. It says things like 'input device', 'output device'. My desktop has an 'input device': the keyboard and an 'output device': the monitor.

Also it talks about detecting structures in a grammar. That has been done before. So putting that on a server and accessing it with input and output devices makes it new and original? Surely an old-style unix terminal running awk on a PL/1 could fit in this broad terminology.
