This effect is already possible - I've been doing this exact thing in a 
project I'm working on, using taper curves. It's quite simple, you 
animate vertex keys on the taper curve to make it grow. It's also much 
more flexible than the proposal, since a) it's a proper 3D shape, b) 
the ends are capped, c) you can change how the stroke of the line looks 
by modifying the taper curve. i.e. in this example, I've left it wavy 
to make it look a bit like a marker pen.
