-Core
-~~~~
-- socket open failure should not be fatal
-- &&,||: priorities
-- static: allow specifying a per-route filter program for setting route attributes?
-
-Globals
-~~~~~~~
-- right usage of DBG vs. debug
-- logging and tracing; use appropriate log levels
-- check incoming packets and log errors!!
-- check log calls for trailing newlines and log levels followed by comma
-- check if all protocols set proper packet priorities and TTL's.
-- try compiling with -Wunused
-- does everybody test return value of sk_open?
-- protocols: implement CLI hooks and per-procotol CLI commands
-- protocols: implement reconfigure hook
-- protocols: use locking
-- check use of system includes and sprintf()

-Various ideas
-~~~~~~~~~~~~~
-- client: Ctrl-R eats one more enter
-- bgp: timing of updates?
-- netlink: import Linux route attributes to our rta's, so that they can be filtered?
-- config: executable config files
-- filters: user defined attributes?
-- io: use poll if available
-- route recalculation timing and flap dampening [see RFC2439 for algorithms]
-- aggregate engine: standard route aggregation and summarization [RFC2519]
-- aggregate engine: injection of manually configured pseudo-static routes
-- generate default route if any working BGP connection exists (aggregate engine again?)
-- generate default route to IGP's (aggregate engine yet another time?)
-- look at RFC 2386 (QoS-based routing)
-- cli: show tables?
