Thanks.

Yes, it sounds like it will be challenging to fit everything in the power budget. Do you think there's a need to use this on battery power? Won't most people be using it in a hotel room? A wall wart that's compact and dual-voltage would work for me and would provide much more power than USB.

I'll also put in a pitch for at least two Ethernet ports, so you can use one for connecting to the hotel and another for your LAN, in case WIFI's not cutting it or you need to connect a non-WIFI device (in my case, a VoIP phone).

One usability problem which has vexed me is that most hotels force you through a captive portal, which doesn't work if you're routing all traffic over a VPN. (Some even make you do it every 24 hours!) My latest solution is a special Ethernet port that's on a separate subnet which isn't routed over the VPN. You use that for going through the captive portal and then you switch over to WIFI or another Ethernet port. I think a hardware switch to turn the VPN on and off would also be a good solution.

There are also software features missing on current devices, especially in stock firmware. A really good firewall, VPN client, and other security tools would be nice. Central enterprise management and/or managed service as an option would also be wonderful. My main goal is execs who travel to China regularly.

For a portable firewall/router, I use a cubieboard running OpenBSD. It has a USB to DC cable that powers the device (no hdd attached) and runs LTE sticks fine. Costs $50 and runs a complete install to run Tor or whatever you want. Right now I have it running pf filtered VLANs to segregate devices, an authenticated AES wireless hotspot and Jondonym mix, which I tunnel all traffic through including Tor and i2p traffic. That way the local wireless carrier who you're using doesn't see any tor traffic.

Yeah, it's definitely suboptimal but it seems to work. If it's easy to have a second radio then you should probably have one. On the other hand, urban areas are usually so saturated with access points that using a separate channel might not gain you much.
