Actually, they could if they wanted to. I remember a paper from a few 
years ago describing how to analyze traffic from a single IP to 
determine exactly how many machines were behind it.

I remember OpenBSD introduced some special randomization features into 
their TCP/IP stack and/or firewall to try to defeat this analysis. IIRC, 
the randomization isn't on by default; you have to enable it in your 
firewall rules.

If it's true that the consumer electronics routers crash at least every 
few months, I think it's safe to assume that they're of such low quality 
that they also don't implement this randomization.

(That's the big reason to run the 486 firewall -- there are 
pre-configured firewalls-on-a-floppy-or-cd which you stick in the drive, 
turn the box on, and reboot maybe once a year to put in a disc with a 
newer release.)
