Hi Ondrej,

I like the idea of moving sage.calculus over to SymPy, hopefully as
seamlessly as possible.  But right now I am wondering if it wouldn't
be possible to vastly speed up the interface between Sage and maxima,
so that sage.calculus could run at something like the speed of Maxima.
 I don't see why the pseudo-tty interface should be so slow.  Probably
the time is spent translating between Python form and maxima?  Maybe
it would be possible to greatly speed this up?  What do you think?

The other thing I think needs attention is the notebook interface.
Specifically, making a system where  it would be easy to administer
accounts on a Sage server.  That would make it very easy to use Sage
in a class.   I would also like to see improvements to the notebook
interface, with hierarchies of cells that could be expanded or hidden.

These are the directions that, for my purposes of teaching and
research, would make Sage a better substitute for Maple and
Mathematica.  Maybe I could get some students here at Dartmouth to
work on this.  But, I'm not sure what skills they would need.
Hopefully, these would be projects that good enough students could
quickly get going on, even if they started knowing nothing about
Python.  Again, what do you think?

Cheers,

Peter
