You're right.

That's the same than putting the code in a lib.

That's not right, there are no things as transparent widgets, as then they
are
unusable. What we really use are tinted transparent widgets, and I think it
would
be a bad idea to not let people have different tints for each konsole
(depending
for example on the real computer the shell is running).

Anyway, I agree that there should be a good way to "share" the background
pixmap (and then apply the tint with a lib call e.g.), and your proposal
is a very good start.

I think in xearth :-), have a look at this page :
http://wwwrzstud.rz.uni-karlsruhe.de/~uddn/xglobe/

and a nice screenshot here:
http://wwwrzstud.rz.uni-karlsruhe.de/~uddn/xglobe/screenshot5.html

I've just downloaded it, so I don't know how it works exactly.
Anyway, I'll have a look now.
Btw, IMO, we should think of adding xglobe to KDE2.0
