I noticed from your earlier statement that you're using the v1 directory
format. This is obsolete, and any v1 directories you may run across
will likely not contain complete information anymore (this includes the
output of the scripts at serifos, which haven't been upgraded yet). See
http://tor.eff.org/svn/trunk/doc/dir-spec.txt for the v2 format
(introduced in Tor 0.1.1.x), which involves fetching network-statuses
and server descriptors independently.

If you want your Tor controller to have up to date descriptors and
network statuses, you can

1) Read them out of the $datadir yourself, from "cached-routers*" and
"cached-status/*"

2) Listen for "newdesc" events, and ask us why there is no "newstatus"
event. (Good point, I've just put that on the todo list.)

3) Send "getinfo desc/all-recent" and "getinfo network-status". This
won't give you the full set of network-status strings though.

4) Turn on your dirport and send "getinfo dir/status/all" and
"getinfo dir/server/all".

Personally, I would go for #4. Note that for any of these, you may want
to set your FetchUselessDescriptors torrc variable (see man page).

(I'm using Tor 0.1.2.1-alpha. I don't recall if all of these are
implemented in the 0.1.1.x series, but it's possible they're not.)

Yep. Especially if you help us figure out what interface you want. :)
