+KEEP IT SIMPLE, STUPID!
+-----------------------
+
+Ideas are all over the place for this project. When adding something, let's
+make sure it's reasonnable to do so and doesn't burden the user with some
+overcomplicated concepts. We want the minimal and most elegant solution that
+achieves our goals.

+TASK LIST
+=========
+
+- Highest priority: pagehash, sign
+- Medium priority: dht, ep, dep
+
+Fix page hash semantics (pagehash, EASY)
+-----------------------
+
+Store and transmit the term binary and not the term itself so that
+we are sure serialization is unique and hash is the same everywhere.
+
+Terminology: stop using the word "block", use "page" everywhere.
+

DHT to find peers for a given shard (dht, EASY)
-----------------------------------
First option: use a library for MLDHT, makes everything simple but
makes us use UDP which does not work with Tor (can fix this later).
-Second option: custom DHT protocol.

-Block store root & GC handling (gc, QUITE EASY)

-blocks.

-The block store keeps all pages that have been put for a given
-delay. Once the delay is passed, the pages are purged if they are
-not required by a root we want to keep.

-Partial sync/background pull for big objects (bg, req: gc, QUITE EASY)

-Implement the copy protocol as a lazy call that launches the copy
-in background.

-Remove the callback possibility in MerkleSearchTree.merge so that
-pulling all the data is not required for a merge. The callback can
-be only called on the items that are new in the last n (ex. 100)
-items of the resulting tree, this is not implemented in the MST but
-in the app that uses it since it is application specific.

Partial merges, background pulls, caching (cache, req: bg, HARD)

+Shard dependency management (dep, MED)
+---------------------------
+
+Some Shards may pull other shards in, under certain conditions. For example
+a stored folder shard will just be a list of other shards that we all pull in.
+
+We want a way to have toplevel shards, shards that are dependencies of
+toplevel shards, and shards that we keep for a number of days as a cache but
