Aside from being in a completely different chapter than the other Hacking Programs, does Hitchhiker (p139) have a cost or availability?

[Dreamwalker]

Its referred to as a hacking program, so the cyberprogram, hacking entry of the software table on page 272 in the CRBs gear chapter (City Edition Seattle) should apply.

[Lewis Greywolf]

It was originally introduced in Third Parallel and just reprinted in H&S. It has the same cost and availability as any other standard hacking program listed in the CRB.
