Hello:

I am interested in it. Thanks.

Everyone:

 I've hacked the TCP/IP stack for Linux to support an ICMP version of the
location idea that I've been talking about. I've also built a simple demon
process that runs in the user space that handles the more complete location
information. I'll be finished with it sometime by the middle of February.
I'm trying to find out if any one else is interested in it. If so I release
the software to those of you on this group. The idea is to have something to
play with (handling both levels of the stack) and get some hands-on
experience. If you are interested let me know.

Chuck Wegrzyn
