There's a reason I don't use KDE...
(Well, a couple actually, the indexing getting pulled in is only part of 
it, I also dislike the all-or-nothing packaging (everything seems to 
depend on everything else), and having to update the whole thing in 
lock-step; somewhat ironically, GNOME has the same issues these days, so 
I don't use that either).

That aside, it's probably worth noting that updatedb used by 
{,m,s}locate only indexes metadata, and it does so a lot more 
efficiently than most of the desktop search-engine indexers out there, 
so it's not quite as bad as baloo or tracker or some of the other 
options.  Unlike those, updatedb pretty much just calls stat on 
everything it's told to index, which takes time, but is not particularly 
bad for your cache if you're just running it on your home directory.

For those who might be interested, autofs is wonderful for handling 
stuff like this.
