I don't see how using a raq is any different than setting up a *nix
box at home behind dhcp or pppoe.  You have basically two options - 
you either manually grab the address from the Raq/Qube/*nix box (if 
it's the primary interface to the rest of the internet), or you bounce
a http request off a 'who am i' web server set to echo $REMOTE_HOST.

Either way, at the end of this, you'll have your IP address du jour
(d'heur, du minute, whatever).  You then update whatever primary DNS
site you use that is friendly to sub-day updates.  There are two that
I know of, DynDNS.ord and DHS.org.

I've used both, and am happy with both.  I used DHS to simply create
a foo.dhs.org subdomain (back when SpeakEasy didn't suck for me) for
a static IP.  About the time I switched DSL providers, DHS was sending
out doom-and-gloom emails about them ceasing operations due to lack
of funding.  I moved over to dyndns.org, and found their dynamic DNS
support and howto's to be incredibly easy to follow.  

My setup: I'm on PacHell PPPoE behind an SMC Barricade.  There's supposed
to be a dyndns SMC client, but I couldn't get it to work, so I just used
the $REMOTE_HOST solution.  On their site they have available for download
a perl script that does the $REMOTE_HOST request, updates a local cache,
and talks whatever protocol dyndns.org uses to authenticate and request 
an update.  I have the perl script configured to run hourly, and the 
updates seem to appear soon after.  Soon enough so I haven't spent any
effort actually clocking the delay, if that says anything.
