How's about something that I could put in my window (or roof)

Sure. No problem. Two boxes and two antennas. One box is a wireless
client, that connects to whatever on Ch 1. The other is a common
wireless access point (or wireless router with the router section
ignored), to which you connect to on Ch 11. They are connected
together with an ethernet cable between LAN ports. (You might need a
crossover cable).

However, if you're going put all this stuff on the roof, you might as
well just put the wireless client radio on Ch 1 on the roof, use PoE
to deliver power via CAT5, and put the wireless access point on CH11
inside the house.

I've done this using a Mac Mini [a] on the window shelf,
taking that signal and "sharing it via ethernet"
out to an Airport on a different channel.

[a] it has a built in 802.11 card

No problem. Basically, you're using the Mac Mini as a wireless
ethernet client radio. See the FAQ at:
<http://wireless.wikia.com/wiki/Wi-Fi#Wireless_Ethernet_Bridges>
Not all of these will work. Verify that it has a "client mode"
feature.

I haven't been able to do complete speed diagnostics,
but I know it works...

Back to back radios work just fine. No self-interfernce, no slow
down, and tolerable flow control (due to ethernet).

Is there a commercial grade "box" that has this
all built in? I've looked around a bit and haven't
found one, but it's such an obvious applicaation
I must be missing the obvious.

Probably, but methinks you could easily build your own out of
commercial hardware. If not, look for a box that has dual radios.

Price, within reason, isn't a concern.

Yeah sure. That's what they all say just before they start
negotiating the price downwards.
