The License might be displayed by the startup banner.

Clearly, there are several possibilities here:
write a texinfo2texmacs converter, or customize the texinfo2html
converter such that the generated pages are a bit smaller.
What about searching the help files by the way?

Yes, documentation may indeed be far more intelligent.
We might want to make it possible to include example sessions
inside the documentations, or scripts which produce examples.
I guess that this may require some changes to be made directly
in the documentation. Would texinfo support this?
It may also be nice to develop "demo modes" which would for instance
allow to run the standard demos for GNU R or Scilab inside TeXmacs.
Notice that it is already possible to send next suggested inputs
in computer algebra sessions (in a similar way as sending prompts).
In any case, this requires some changes in the interfaces.

A first step would clearly be to provide help for CAS' where
no online help is available yet (Yacas for instance).
A next step might be to contact the developers of different CAS' and
see how to support interactive help (which is different from online
help: think about typing something like "?command" in a session).
Solving the interactive help brings us naturally to interactive
Finally, for even more integrated help, we might try to figure out
how to enrich existing documentation in such a way that it becomes
more powerful for interaction with TeXmacs. Since this might require
some changes in the help files themselves, we would have to figure
out a suitable format for each CAS (modified texinfo, TeX/LaTeX or
Html with additional markup, etc.).
Of course, all help from the maintainers of the different
CAS systems would be very welcome too.
In any case, thanks a lot for your proposal !!!
