Thanks for pointing this out, I haven't checked until now:
* [Redis](https://github.com/antirez/redis): no NOTICE file in project
root, anything similar is for their dependencies under
[deps](https://github.com/antirez/redis/tree/unstable/deps). They have this
[info](http://redis.io/topics/license) on their website.
* [Memcached](https://github.com/memcached/memcached): no NOTICE att all,
one [COPYING](https://github.com/memcached/memcached/blob/master/COPYING) which
is actually a new BSD license
* [LevelDB JNI](https://github.com/fusesource/leveldbjni): nothing in
this range. However It was important to double-check this as we're not actually
depending on LevelDB, but on this related project. This is also under new BSD
fortunately.
