It's not supported by the plugin. There are hooks for polylines in  
the API though, I once implemented those using Balloon2D (meaning  
they could not be hidden behind a 3D mesh). Very long time ago, not  
sure if I can find it - it was more a hack than anything else.

Your best bet would be to just construct a tube mesh connecting the  
nodes.
