I use DynDNS.org for a couple domains, and the only problem I had was  
a misconfigured client that started spamming them with update  
requests multiple times per second. IPCop Linux and Linksys router/ 
firewalls both handle dyndns.org stuff great. DynDNS will drop the  
domain if you don't update it enough (i'm guessing this is to handle  
people that simply unplug their machines and never think again about  
it), but they email you if this is the case. I got a couple such  
emails with the Linksys router, but it updated automatically right  
after those emails were sent out. IPCop "just works".

and the one time I updated *way* too often, they emailed me telling  
me they disabled the domain from updating, I logged into the site,  
and needed to give them a reason for the problem. Once I clicked  
"send" on the website, it was turned back on, so I really think this  
policy is in place so they can drop abusers off the service. Using  
one of the preconfigured clients, like what's in IPCop Linux or the  
Linksys routers 99.995% of the time won't get you any problems (the  
only way you can get a prob is if you sit there and keep clicking the  
update button).
