So, there are 2 ways to get eCos WiFi driven devices: either upgrade HW
to the linux battteries (= *PCI) or downgrade... to the PIC interfaces
(= RC232*) if you can use clever WiFi module there. For the "downgrade"
way, you can look at WIZ-600Wi module, for example, from WIZNET. It has
both MII and RS232 :) interfaces and some firmware binary for download
