FYI, these are mostly "home" devices. These may well work for a couple
of devices. Expect failures/performance drop when doing more devices
doing a lot of sessions (Skype/bittorrent) by running out of memory
and/or get overheated. 

Scalable options:
- let ap bridge
- let XS do nat/route/cache

Securing channel/auth drops performance of ap

options:
- in wnic encryption (driver/firmware issue)
- usage of vpn (ipsec/openvpn)
- hardware crypto support in ap or or in the XS

kind regards,
Marten
