This doesn't answer your questions about Ruby, but most of what you want 
exists already.

Look at http://www.dyndns.org. I've been using them for a year or so. 
Every 5 minutes, a Perl daemon (ddclient) on my system wakes up, grabs 
the WAN address from my Linksys box, and if it's changed, updates 
dyndns. I can ssh into my system at home using the name 
'tidal.dyndns.org', even though the address actually belongs to my ISP. 
It works great, and it's free.
