Agreed, I'm a fan of it too, and if I ever have some Copious Free Time I'm 
going to have a bash at making some packages for it (Shorewall and Postfix 
spring to mind).

A good tip from their website is to use a security bug in the Linksys 
webserver to run some NVRAM commands on your system to set up the boot_wait 
flag on. This means that on every reboot the box will wait for a flash 
upgrade via TFTP on for a few seconds so that if you do 
completely botch it you can recover. :-)

The hack tricks the system into doing:

cp */*/nvram /tmp/n
*/n set boot_wait=on
*/n commit
*/n show

The joy of it is that you can grab everything you need from CVS and fix it if 
you know how to! :-)

This is one of the reasons I reckon Shorewall would be a great package to port 
to it, first off it should be relatively easy as it's all shell scripts and 
secondly it does all the hard work with iptables for you. :-)

Yeah, and from some of what I've seen about their practices I'd rather stear 
well clear of them.
