this sounds interesting. are there any screenshots? did you allready
implement it? Is it really better, than what we have kludged?

What does not kill you, makes you stronger.

I'm a bit sceptical about this. I would not say, that writing own vector

There are other interesting grass-python bindings. I hope, they will
arrive to grass-dev list soon ;)
