I'm not sure that the setup cost would be any more for either method.  
The fulltext search would most likely use more memory, have more 
dependencies (depending on a number of factors).  and require more disk 
space.  None of these things are deal breakers though, especially given 
the advantages.

The indexing delay should not have much effect on performance just a 
'lag' on being able to search for a new or updated item. Also, as i said 
in the wiki, I think the only noticeable delay would be when a repo is 
synced and we try to re-index the packages and errata.  Generally any 
update or create would be handled in the background as the create or 
update occurs.  So generally before the user would be able to search for 
the updated item, it would be updated.
