hi,

Glad to note that more of you like the sound of this.

Always nice to see more Python'ers. :)

Sure, so long as vtkpython will work - go right ahead.  One thing
please don't throw in a "Using vtkpython is obsolete" message when
someone uses vtkpython.

Actually, the vtkPipeline stuff is mentioned at Sebastiens site.  In
fact almost any important VTK code out there is mentioned at there. :)

I will work on making a quick and dirty version ready for now and mail
it here.  I'll let you folks play with it for a while.  Next weekend,
I will spend more time on it after I get some feedback from you.  Once
we are clear of how it should fit in with the current tree and test
suites I can commit it to CVS etc.

Thanks for all the feedback.
