It could, with an appropriate model-view implementation.  For some
reason it wasn't produced that way, and I don't know the design
decisions behind that.  Probably convenience?

In general, there is not much motivation here to produce non-graphical
versions of everything.  DrScheme is our flagship product, so we
mainly want tools that will run under that banner.  Yes, there are
deployment concerns, but development tools usually aren't needed on
deployment platforms (eg, develop under NT, run on CE).

DrScheme Jr should work well within Emacs (which, I presume, is the
context that interests you).
