I posted a "me too" sort of response early in this thread, so here's an update of what I have learned and figured out.

2 days ago I had heard of ad-hoc wireless networks, but really didn't know anything about them or what they really were.  I looked into this a bit further on the advice of someone who posted a reply in this thread and it turns out this meets my needs quite well.  There are simple instructions for setting up a gumstix (with a wifi interface) here:

    http://wiki.gumstix.org/index.php?title=Creating_an_Ad-hoc_Wireless_Network

In the end (after about 5 minutes of copy pasting commands from the wiki) I have a new wireless network running from the gumstix, along with a dhcp server.  I can see this network from my tablet or my laptop (or my friend's ipad) and any of them can connect and get an IP address.  Once connected, all the machines can see each other via their IP addresses.

I don't know if it's possible to to route traffic to the rest of the internet if the gumstix is connected via ethernet to the world, but that would be a fun little extension if it wasn't too hard to do.  It's probably standard linux network admin stuff, but I personally have never had to travel down that path so I don't know what the details might be to make something like that work.

Also this network runs with no security or password.  It might be interesting to explore if it's possible to set up at least a simple password for access?

Thanks,

Curt.

I think first place to check/ask are the kernel mailing lists. For
this issue I would look at [1].
