As several have expressed interest, a plan was agreed on meeting today :

- I will create a (temporal) new branch on svn where i will commit  
the 2.44
ported  patch (Note it probably wont be a working one, as the initial  
patch
assumed windows only, and i tweaked some bits).

- From there, Ettore can work on the same code as us, working on the  
plug-in
for all platforms 3Dconnexion support, which is what he said he was  
working on.
Do i'm right it is linux, windows, macos X ?
For macos X, it is ok to weak link the plug-in to the driver framework.

To avoid license troubles, we cannot host the plug-in code on our  
blender svn.
Either 3Dconnexion will have to host it, or we put it somewhere else.
The plug-in code  (one tiny cpp file, could be C) must be LGPL.

- In the mean time, i will work on adding HID support to ghost. HID,  
being a much
general solution, provide us a more versatile tool, but only for USB  
devices.
More work, but better in the long term. Having the 2 solutions in is  
the best deal.

- We thought about using 3 modes :

*  moving object selection with or without dominant mode (basically  
it is a transform
    of the object)
*  moving the view camera.

- I will create a wiki page where we can discuss the features we want

I take the ownership of the branch, meaning it is my duty to kept it  
in sync with trunk.
Non bf-commiters can send me patches i will apply to svn.

I will create the branch and wiki after having heard your comments if  
needed,
probably tomorrow.
