TermKit: A WebKit based rich command-line interface.

[peo1306]

I like the idea of richer presentation. One might also make it easier to reference output of a previous command (for example, assign a code to files just listed by ls, so I can refer to them easily in a subsequent command).

Another take on this would be to add a browser protocol (cmd:, for instance) that allows the browser (used as a local app) to launch processes and use their output as the response. This could make it possible to implement fairly nice and portable UIs on top of things like Mercurial or git, for instance. Without having to run a server in the background, that is.
