Sure. Create yourself an account on
http://www.sagenb.org/
You do not need to download anything, as you will be using a server hosted
somewhere else. The admin of the server will probably put limits on the amount
of RAM and CPU time you can use, so there are advantages to having a local
server. If it's local, you just connect your browser to
http://localhost:8000

Yes.
In fact, neither you nor the other person need to have Sage installed.
There needs to be a Sage server, but that can be on your machine, his, or a a
publicly accessible Sage server thousands of miles away.
The communication can be via HTTPS, using encrypted traffic, so it is suitable
for commercial purposes, where standard HTTP does not offer sufficient security.
It goes without saying, if the information is highly confidential, it would be
unwise to run it on a public server. The admin of the system could read your files.
I should add at this point my knowledge of using Sage is *very* minimal. But I
do spend some of my spare time developing it. My aim it to get better Solaris
support.
Sage now runs fine on Solaris (SPARC) though building it is a bit tricky. It's
not running well on OpenSolaris, though I hope to fix that, as I just bought a
Sun Ultra 27 with a quad core 3.33 GHz Xeon and 12 GB RAM!

Sage works as a client/server just like a normal web site. You do not need to
download anything to read HTML.

See above.

I do not think it has ever been like that. I think you mis-understood the
concept. But I may be wrong. I know it does not work like that now.
There will be more limitations using a public server. If you want someone else
to be able to run some CPU intensive stuff you wrote, then you would need to
install your own Sage server, and give them access to that.

But the Mathematica solution is limited, as the other person can not change the
code. But in Sage, you can allow others to edit your notebooks.

Run yes, but due to license restrictions, I very much doubt Wolfram Research
will let anyone you choose make any changes they want.

Jobs requiring skills in MATLAB are quite common in engineering.

Sage does not have its own langague like MATLAB, Maple or Mathematica. Sage uses
Python. So you would need to learn Python, for which there are many jobs!!

Yes, it will. I hope none of the commercial vendors go out of business, as
competition always enhances products. I doubt modern CPUs would be as good as
they are, if there was not the competition between Intel and AMD.
