Yes, more or less. I am suggesting that people who have *detected* a 
vulnerability and wish to publicize this fact should publish their lists 
in a standard format and make it available via a standard protocol like 
LDAP. Since the number of *detected* vulnerable hosts is a lot lower than 
the total number of vulnerable hosts this is not as big as you think. And 
since one has to *detect* the vulnerability before publishing it, the 
scaling issue with detection is more of an issue than with publishing.

Besides LDAP has proven to be scalable to very large databases. LDAP was 
developed as a light-weight system so that it could be scaled massively.

Sure, why not? If someone is going to the trouble of collecting the 
information and publishing it, then they should publish this as well. 
After all, when you query an LDAP server you can specify which fields you 
want to retrieve. Applications that don't need the vulnerability info 
won't bother asking for it.
