Sure thing.  If y'all think of it, it might be good to put some more 
error reporting into the ipa-replica-prepare tool.  The debug log didn't 
seem to be much help (to my n00b eyes).  Ultimately it was the error 
message from "ipa cert-request", "Profile caIPAserviceCert Not Found" 
which lead me to the solution.  If it's hard to add it to the tool, then 
tossing stuff like that into the logs would help too.

Just a suggestion, since with such awesome tooling (graphical and CLI) 
on a project like this, it's bound to attract more n00bs like me.  The 
DNS/Kerberos stuff is straight forward because there's lots of 
deployments and a long history of mailing list posts to find answers on. 
  The cert. system seems to be a different story entirely, it's 
(arguably) as powerful as kerberos but doesn't get nearly as much 
"press" coverage :D
