If the openwrt folks could figure out how they are going to deal with NAND
flash, it would be nice to be able to use one of the many routers that is
shipping with more flash (128M in the newer netgear routers would be nice)
if I were to get my hands on one, what sort of testing would you want to
do to it to tell if it looks like it would hold up?
I have experience running mtd on NAND, using jffs2. It seems to be holding
up well. Better than NOR did, honestly. Although in general, I wish they
would shift to eMMC. But it's driven by two factors:
1) part cost
2) chipset support from the router SoC vendors
Given some of the wishes that I see on here, I think for development,
people would be happier with a platform that wasn't based on a router SoC
(like the wndr is), but instead was based on an embedded application
processor with PCIe for the radios, and an external switch fabric.
I think we have two competing desires.
one is to have a nice powerful device for those people who have fast connections
and for us to experiment with.
the second is to have a 'home' device.
using a 3800 or similarly priced ($100-$150 USD) device that's readily available
is very good for the second category, the question is if we can find one that's
powerful enough for the first.

But for
thermal purposes alone, I've been seeing more and more external switch
fabrics. The heat of a 5-port gigabit switch IC is pretty substantial
(from my teardowns).
One item I think will be a boon, especially with DNSSEC, is super-cap or
battery-backed rtc, but that's asking for a unicorn, I think. Or... a
Gateworks Ventana GW5310 loaded with a couple standard (industrial-grade)
PCIe radios, loaded into a custom case. My guess is that it's a pretty
expensive route, though. I would be surprised if a completely assembled
unit would be <$300. At which point it starts to look better to just run a
separate router and AP (using standard wndr-type platforms as the APs and a
higher-end board or PC as the gateway).
