I run two Alixes (Ali?) as firewalls at two sites, both running a
stripped-down version of the CentOS 5 distro, and connected to 
each other, my outside servers, and road warriors with OpenVPN.  
I have not seen the failures Chris talks about, though I keep a
third ALIX ready as a spare, just in case.

I don't really know about performance.  They move unencrypted 
bits through the FIOS link just fine (15Mbps upload, 5Mbps
download, as advertised), and rsync backups over the VPN
from a server in California are just a little slower. 

The AMD Geode that drives these machines has an encryption engine
that OpenVPN is not currently using.  Perhaps that can help with
speed, if someone tells me how to engage it.  Also, in both cases
I shove all the logging bits (unencrypted) to local servers, so
I do few writes to the compact flash card I use as main storage. 
If I did more local read/writes, I imagine the ALIX would be a
lot slower and less reliable.

I am using "x133" CF cards.  8GB cards are $10 from Newegg, and
I only use about 1.2GB of that.  Are faster cards worth it?

While I do not need Yet Another Spare, it would be good to prove
the usability of these machines, so that more local users would
have them, and more people could teach me to do it right.  So if
anyone can suggest some easy measurements, or do them in their
own lab, perhaps we can demonstrate the quality and speed of
these little machines, either to convince others to join us,
or to find a better alternative.  Either way, we should use
what PTP uses, and leverage from their experience.

If I upgrade from an Alix, I would like something small, X86,
solid state, low power (4 watts or less), and inexpensive. 
I don't know of anything better in that class.
