"It may not be supported initially"

I think it WILL NOT be supported initially, but anything can happen later. Perhaps the Dev Team, or someone else will code support for the Apple Airport wireless card(s), with or without WEP or WPA security active initially and add the security to the wireless driver later. Who knows what is going to happen after MOS for the MacMini is released.

The one thing I do know for sure is that there is a huge amount of interest in running MOS on Apple PPC hardware of any kind and I expect that once MOS for the MacMini is released, we will see an increase in usage and hopefully an increase of programming for apps and games for MOS.
