I'd like to try to create a cheap, small, wireless "server" with
OpenBSD. I'm not sure where I want to start, but I'm not opposed to
soldering individual components, and I'm not opposed to hacking code
(Its my profession after all).

If possible, I'd like to design something that cost less than
(hopefully) $100, and has WiFi support. I'll want enough capability
to SSH into it, perhaps server some small files over HTTP (perhaps
using php). It would be a bonus if I didn't have to cross-compile
programs on a seperate computer to get them working on this box.

So, my guess as to what I need:
WiFi component
Power Supply (preferably solar powered or AA powered, but can do
wired if I absolutely have to)
Processor (cheapest possible with enough speed for what I need)
Memory (again, cheapest possible with enough for what I need)
Storage (you guest it, cheap but enough. I'm thinking 1 gig flash
drive should be enough)
Some way to connect for installation and maintenance.

Good luck with those power requirements. Wi-Fi is not cheap in terms of electricity, especially if you want the normal coverage. There is a reason Nintendo devices are 1mbps with tiny ranges.

You can probably do battery backup, trickle-charged to keep them fresh, but going completely mains-free will be a design challenge. You will have to pick your hardware very carefully, and manage the services even more carefully.

Anyone have some starting points I can look at? The WiFi access
doesn't have to be secured, nothing important will be transmitted
unencrypted anyway.

You should be sending data over an SSH tunnel, anyway. Wi-Fi security is a bad joke.

Am I high thinking I can do this in less that $100? If so, what is a
more reasonable estimate? Price is one of my main driving factors.

If you designed these right and then contracted a third-party to construct hundreds of them, then you /might/ get the cost down to 100 units of your local currency.

Check out "Soekris" and similar offerings. Some people are finding ways of setting up embedded or diskless OBSD edge boxes.
