Adapt to use real roads?

[Patabugen]

It's not entirely clear from the Readme whether it's possible to use this (with a custom distance router, I presume) to calculate real TSPs using real maps (including one-way roads etc).

I'm about to implement something similar in PHP, and would rather contribute to an existing project if I can - but only if it's within the reasonable scope of this project?

Also - are you maintaining this package at all?
