wherein the routing component of the passenger vehicle is configured to relay data responsive to the routing information, and

a transceiver configured to relay at least a portion of the data at least one of to or from the passenger vehicle.

4. The network subsystem of claim 3 , further comprising: a signal-bearing medium bearing at least one instruction for obtaining the suitability indicator as a function of a content of the data.

5. The network subsystem of claim 3 , further comprising: circuitry for obtaining the suitability indicator by means for executing a table look-up command.

6. A network subsystem for connecting a first system to a second system through one or more wireless links, the network subsystem comprising:

a non-transitory device-readable medium bearing one or more instructions that, when executed, route data along a channel through a passenger vehicle determined at least partly based on a vehicle-position-index-dependent and vehicle-heading-dependent suitability indicator of the channel, wherein the suitability indicator being based on at least a speed of the passenger vehicle, a quantity of data being relayed, and a computed distance metric of the channel; and

a module that controls the non-transitory device-readable medium; and

wherein the module further includes a transceiver configured to relay at least a portion of the data at least one of to or from the passenger vehicle.

7. The network subsystem of claim 6 wherein the module further includes:

a calculator that estimates a time when the passenger vehicle is predicted to enter and/or depart a zone boundary of a service zone.

8. The network subsystem of claim 6 wherein the module further includes:

a transceiver configured to provide the data to the non-transitory device-readable medium via a wireless link.

9. A network subsystem comprising:

a mobile system; and

means for transmitting data through the mobile system toward a destination node at least partly based on determining a vehicle-position-index-dependent and vehicle-heading-dependent suitability indicator of a channel, wherein the channel connecting a plurality of nodes including the mobile system and destination node, wherein the vehicle-position-index-dependent and vehicle-heading-dependent suitability indicator being based on at least a speed of the mobile system, a quantity of data being relayed, and a computed distance metric of the channel.

10. The network subsystem of claim 9 wherein the means for transmitting data is aboard the mobile system.

11. The network subsystem of claim 9 wherein the means for transmitting data further comprises:

sending a message responsive to a routing information toward a destination node via the channel, wherein a later received message identifier is compared with the identifier of the sent message.

12. The network subsystem of claim 9 wherein the mobile system includes:

one or more antennas for detecting a position of the mobile system.

13. The network subsystem of claim 9 wherein the mobile system includes:

means for providing electricity to the means for transmitting.

14. The network subsystem of claim 9 wherein the mobile system includes:

means for generating power accessible to the means for transmitting.

15. The network subsystem of claim 9 wherein the mobile system includes:

one or more antennas remote from the mobile system.

16. The network subsystem of claim 9 wherein the means for transmitting includes:

means for generating the suitability indicator as a function of a position index of the mobile system.

17. The network subsystem of claim 9 wherein the means for transmitting includes:

means for communicating with a user aboard the mobile system.

18. The network subsystem of claim 9 wherein the means for transmitting includes:

means for obtaining the suitability indicator by obtaining a vehicular traffic data model.

19. The network subsystem of claim 9 , further comprising:

means for detecting a position of the mobile system.
