I have a Fonera WLAN router (unfortunately it has been offline for a while now, but nevertheless) and I really like their thing. In their blog I read that their next generation WLAN router will be an open platform for developers. Interested developers will be able to join Fonosfera: The FON Development Community. Also worth noting is that The Fonera 2.0 will have a USB port and they plan to make it possible to connect an HSDPA modem for sharing 3G access. Nice!
