Different between Autoroute, mappoint & live earth

Hello boys, I'm new.
I've readden many things about this 3 products, but i dont really understand what are the differences.

I need a software for:
1) Calculate route distance between many cities
2) Optimaze the route
3) Get how i must pay for road and something like this...

who can help me?

I'm a programmer, I've develop a simple software for to get the distance between 2 cities, and it's ok. ( bu live earth SDK). For example: my software send a request to "map point Web Services" ?
If i buy mappoin software can i do it in local machine?

But maybe its better to buy a software that already do that?

Andrea my take is as follows:
There are some obvious differences - Autoroute and Mappoint are on your computer, Live Earth is web access

...but the important ones for usage are
1) Autoroute is not programmable
2) Mappoint is programmable and supports territories and data mapping
3) Live Earth has much wider route calculation range; Autoroute & Mappoint only cover (either) North America or Europe and in Europe coverage of gets worse as you move East. Live Earth allows route calculation in (for instance) Russia, Turkey, China and former Yugoslavia. Incidentally be warned: distances are OK for these places in Live Earth but journey times (based on 50mph average) are unrealistic. Also, all routes are road routes where, say, in Russia trains are the lead transport mode.
Also Live Earth is much better than Google Earth for these journey calcs.
