Possible, see more on my opinion for this later.

I defiantly agree, multiple indexies is a huge waste. However, we do
this with some stuff, like filtering manpages and applications,
perhaps we should consider adding a default system wide index location
(like /var/beagle) and start including all those indexies there.

Agreed.

This is exactly the issue, the static queryiable doesn't handle
live/incremental updates well. (or at all at this point) by having our
own crawling/change/event handling code we can significantly decrease
the overhead of updates.

My other thought is that gentoo's update system does modify a lot of
files, more so than most systems (as there is no real versioning) and
most users just type an emerge --sync or similar and can have 100
ebuilds change a day, and easily over 500 a week. Debian (especially
stable) defiantly leans toward a more static system, but of all the
package managers, I was under the impression that gentoo was the most
dynamic....

My $0.02, just playing devil's advocate to explore everything. Also, I
don't want anyone thinking I'm an authority on any of this, last time
I used gentoo was over a year ago.....
