Yes, this would generally fall into what I've been calling "httools." This
would be a series of simple programs to merge, delete, checkpoint, gather
stats, etc. from the databases. (Insertion obviously still falls under
htdig since "insertion" implies "indexing.")

Yup. It's in there. The current 3-2-x branch allows '-m <filename>' to
only index the URLs in a file and if it doesn't already take this from
STDIN, it will shortly.

Any talk about persistent database connections, multithreading, etc. is
good, but will obviously have to wait a bit. :-)

Yes. Until a very short time ago, it wouldn't have been possible to have a
daemon version of htdig since you had to run htmerge afterwards. There
were a few other issues, but I would suggest that this is a reasonable
goal for 3.3.

For htsearch it's a bit further off since we'd need to work out a variety
of caching and access issues. However, I think it's also a reasonable goal
for 3.3.
