+# Networking
+> Pretty important here
+
+## Auto-connect
+
+Rework the auto-connect system of device blocks to be more stable.
+Prob re-scan the network continuously
+
+## Synchronization
+
+Move the state logic into the node, as it was meant to be.
+Note, addresses on the client are allowed to be complete bullshit at least for a bit of time.
+`ComponentItem`s should no longer allow a node on the client (at least for now), it serves no
+purpose currently, and also is not designed well.
+
+## Get rid of NodeBlockEntity
+
+It is basically throw-away stitched together garbage.
+Replace it with a new abstract class, which allows different nodes on different sides,
+handles synchronizing those nodes according to their state changes.
+
+Also implement an equivalent for LivingEntities, like drones or other addon stuff.
+
+## Optimizations
+
+Optimize the networking, both synchronization using smaller encodings,
+and emitting messages or adding/removing nodes. The goal is to have as little of
+the CPU time on the server thread taken by NC as we can.
+
+# Computation
+> Pretty important for a computer mod
+
+## JNI
+
+We need the JNI system so we can salvage our hard labor thrown into NeoNucleus.
+Also because it is a capable engine and has a good API for architectures, and NCL is very capable.
+
+## Worker threads
+
+Computers need worker threads for running non-synchronized code, because otherwise we're cooked
