It would only tell them I'm not running windoze.  However, that doesn't 
necessarily mean I'm nat'ing a lan behind my box.  And, running an OS 
other than windoze or mac doesn't violate the service agreement in 
_most_ cases.

I agree.  I'm the customer an ISP should love to having.  All I need them to do 
is handle their end, I'll do the rest...thank you.

I could understand them getting upset with people running big websites on 
their network and hogging bandwidth.  Fine crack down on that.  But don't 
hassle me for handling my own email and having a hobby website.

There are devices that do just that, can't recall the brand, maybe netgear.
It will be a cable or dsl 'modem' and then serves as a 802.11b wireless access
point for the rest of your home network.
