BTW, if you can find a Postscript printer with a serial port, you can log in via an ascii terminal & get a read-eval-print loop. The default is to _not_ echo the characters you type in, so unless you twiddle a bit somewhere inside the printer, you'll be typing blind.
It may be possible to log into your Postscript printer over the network via telnet, although I haven't tried it.

With emacs, you can edit the ps, then ctrl-c ctrl-c renders the image (bound to 'doc-view-toggle-display'). The same keystrokes bring back the source code when viewing the image. Also works for pdf, pnm, svg (and others). Very convenient indeed! cf. http://xkcd.com/378/
