Only in limited spaces, hardly a blanket over a whole country. In NL
it's only at certain hotspots, and even then it's very limited
bandwidth. (and expensive)

I don't want to play music on my phone. I just want to make calls...
so for me that's about 5 or 6 hours of calling time. (sidenote:
standby time is also drastically cut when you have your wifi turned
on, those things can be real power consumers, my Nintendo DS can
normally play for about 16 hours non-stop, when I turn on the wifi,
suddenly I can only play about 8 hours non-stop, not that I do that
very much)

Half of 5 hours is how much? (to go on with the iphone example)
Right... 2.5 hours of talking time. And that's for the service of
truphone alone... that's not including the draining that's done by the
wifi-chip.
BTW, do you own stock of Truphone? Or are you in any other way
affiliated with that product? Just curious.

So they admit that there is a drop in battery life when using the
product. Because, to preserve battery-life you have to turn WLAN off.
Also it may be so that Truphone doesn't really affect standby time,
but Truphone is only the product you use. It's not the Wifi chip
that's in your phone.
And it's that Wifi chip that's causing the drainage, it needs to sync
regularly with your wireless router or whatever accesspoint you have.
Besides it's a moot point, there is currently *no* open source
low-power wifi-chip. And Sean and the rest of the OpenMoko team has
indicated that they have no interest in adding a closed-source
closed-spec'ed piece of hardware in there almost completely open
phone. (What would then be the use of making the rest of it completely
open, if they did?)

No, we just think it's improper to demand that the OpenMoko team
should go back to the drawing table to add a proprietary wifi chip on
the board. Completely destroying months (or perhaps years) work, and
demand that they do it in a few months!
(you give me the impression that you think it's no big deal to just
add a little chip in it, and that they absolutely right now have to do
it.)
