+Quick TODO --------------------------------------------------------------------
+
+- cleanup core/comm usb stuff 
+- support i2c in hardware (and a soft master mode?)
+- cleanup license headers
+
+Peripherals -------------------------------------------------------------------
+
+- complete timers and interrupt stuff
+- I2C
+- SPI
+- EEPROM
+
+Arduino Library functions to port (these are LGPL) ----------------------------
+
+EEPROM:
+    functions:
+        uint8 read(int)
+        void write(int, uint8)
+
+Servo:
+    modify timer code, "banks" of pins corresponding to a timer
+
+Firmata:
+    edit Firmata.h for capabilities
+
+Matrix:
+    soft spi port stuff
+
+SoftwareSerial:
+    clockCyclesToMicroseconds(int)
+
+Sprite:
+    all good?
+
+LiquidCrystal:
+    timing on soft serial send() commands
+
+Stepper:
+    requires millis()
+
+Wire:
+    reimplementation of the utility/twi.{c/h} code:
+        void twi_init(void);
+        void twi_setAddress(uint8_t);
+        uint8_t twi_readFrom(uint8_t, uint8_t*, uint8_t);
+        uint8_t twi_writeTo(uint8_t, uint8_t*, uint8_t, uint8_t);
+        uint8_t twi_transmit(uint8_t*, uint8_t);
+        void twi_attachSlaveRxEvent( void (*)(uint8_t*, int) );
+        void twi_attachSlaveTxEvent( void (*)(void) );
+        void twi_reply(uint8_t);
+        void twi_stop(void);
+        void twi_releaseBus(void);
+
+Ethernet:
+    ho baby...
+    uses avr/interrupt.h
+    reimplement utility/spi stuff
+
