+# Multiarch / Ports
+
+* Split out x86 / PC-specific bits into new arch/ directories
+* Fix up uses of explicitly sized types where possible
+* x86-64 port
+  * Good for verification of multi-arch readiness
+  * Much easier to develop for than ARM port
+* ARMv6 port is underway
+
+# Cleanup and POSIX expansion
+
+* Rewrite underlying process model
+  * `task`/`process` split should match architecture dependency split
+  * Better allocation management, process tracking
+  * Cleanup is a pain right now - we need to stop eating processes that finish with parents that might want their statuses.
+  * Sleeping, wait queues, and IO polling/select depend on some rewriting
+
+# New EXT2 drivers
+
+* The EXT2 drivers are poorly written, they need a complete rewrite
+* Allow for multiple EXT2 instances
+* Operate on block devices rather than directly with ATA drives
+  * Allows for effortless ramdisk implementation with same code
+  * Will make MMC port a lot easier for RPi
