Indeed it does.
One feature that I could not find in your demos was drawing rubber band

It's there -- it was integrated ith teh Zoom-In functionality, but I pulled
out a version and put it in:
floatcanvas.utilities.GUI
It provides a "GUI Mode" that lets the user draw a rubber band box.
I'm not sure if there is a demo on using it anywhere at the moment, though.
Also, when I tried the demo MovingElements.py I got the following
error: *NameError:

Looking at the code I"ve got, it works fine, but I see that it doesn't
import BBox if it's run with the installed version. You'll need to add:
from wx.lib.floatcanvas.Utilities import BBox
to the 'installed' import black.
I've added that to SVN.
Also, in the future, how can update floatcanvas to the latest release?

I _should_ have a proper setup.py, but in the meantime, what I would do is
add a floatcanvas directory right in your code, and do an svn checkout in
there.
Then adjust your imports so that that version gets found.
You can then simply do an svn update to get the latest version.
If you happen to be using subversion to manage your own code, this could
get confused, in which case, I'd put floatcanvas in an external directory
and and make sure that you can import it one way or another.
You _could_ also copy the SVN version on top of the version in wx.lib, but
I think that's kind of fragile if you update wx, for instance.
If anyone wants to write a setup.py that will install it into its own
namespace as a package, I'll add that to the distribution -- it would be
nice to be abel to simply do:
./setup.py install
or
./setup.py develop
and be done with it.
