With your standard RJ-45 NICs, you can connect two computers directly together with a cross-over cable.  Is there anything like this in the wireless world; can two computers with wireless NICs be "hooked" together without a third network device?

If not, are there portable wireless hubs, etc?

I basically have a situation where two people with laptops, each with wireless cards, will be traveling together and need to share data.

Obviously, the cross-over cable is an option, but just wondering if there was a wireless solution.
