One thing we've been kicking around lately was a dream-list feature of 
"throw a contextcsn on any arbitrary entry." Our motivating problem was 
essentially

+ dc=syncproved,dc=rutgers,dc=edu
	+ ou=Boot-Time Configuration
	+ ou=Dynamic Configuration

We wanted the ability to arbitrarily add a contextcsn attribute into 
"ou=Boot-Time Configuration,dc=syncproved,dc=rutgers,dc=edu" despite the 
fact that the suffix/syncprov was on "dc=syncproved,dc=rutgers,dc=edu". 
This would be combined with, essentially,

/* if bootconfig is fresher than we are, reboot to get it */
if (contextcsn(BootConfig) > (``date`-/proc/uptime`)) restart;

to get things that can only be configured at boot time.

(No, we're not actualy that crazy with our systems, it's just a daemon; 
but you get the idea.)



In the end, we're just searching for entryCSN>=lastRestart with base of 
ou=Boot-Time. But contextCSN seems more eloquent (only pick up one 
entry) and this might be (roughly) in line with what you were considering, 
or give you some ideas (ridiculous though they might be).
