On the name thing, I read something on the Wippies support forums that you could rename the access point. Is it possible people are renaming theirs and accidentally making it impossible to tell it's Wippies? If so that's rather a stupid option... :-)
I would still worry about how the ISPs would react though, which makes it interesting that Saunalahti are doing this because they're an ISP too.
Someone on the Wippies board suggested that Saunalahti should give away free access to anyone who sets up a Wippies router, which might be an interesting way to grow the network quickly.
Like you say though, if the network can't be picked up in the street or nearby buildings, there's no point in building it.

I can't remember much from physics lessons, but could it be that Wimax's higher frequencies penetrate further through walls etc?

Higher frequency penetrates less. Higher the frequency, more line-of-sight connection is needed.
Operator run wimax basestations can use much more power. For example 3G basestations can have 40 W or even 60 W antenna power. High power transmitter needs network planning and guarantee that nobody else is using the same frequency. That's why operators need lisenced spectrum.
I guess that wimax has better channel coding than 802.11b/g which would mean slightly better performance. But 802.11n (the new wi-fi) is giving the same promises for consumer level wireless network. Given that I haven't seen any wimax basestations for consumer market and 802.11n-draft basestations have been sold "for ages" means that most likely 802.11 is the way for homes.

So is there any standard likely to be available to consumers which will be able to reliably transmit to people in the street outside?
