Is there any way to have the ARDUINO IDE use the cores from this, or even use 
the IDE as a front end GUI for this, or have a GUI implemented for this.

I miss A0-An definitions for analog pins.

When i want to set analog pins to in/out or doing digital write/read i have to 
calculate the pin number, so i added some definitions to arduino_lit.h, i don't 
know if this is the proper way/file to do it, but works for me:

#if defined(__AVR_ATmega1280__) || defined(__AVR_ATmega2560__)
    #define A0  54
    #define A1  55
    #define A2  56
    #define A3  57
    #define A4  58
    #define A5  59
    #define A6  60
    #define A7  61
    #define A8  62
    #define A9  63
    #define A10 64
    #define A11 65
    #define A12 66
    #define A13 67
    #define A14 68
    #define A15 69
#else
    #define A0  14
    #define A1  15
    #define A2  16
    #define A3  17
    #define A4  18
    #define A5  19
    #define A6  20
    #define A7  21
#endif

Not really a issue but figured better here than email someone directly.

The google code project suggests the code is released unter LGPL 
(I am trying to build a small autopilot using it and wanted to know the 
licensing before hand ;))
Is that correct? I was not able to find any license related info in the 
repository.

Best regards and really awesome library!

There is an error in wiring_analog.c line 50.

ADMUX = (analog_reference << 6) | (pin & 0x0F);

ADMUX bit 3 is not channel selection bit, so the original arduino looks the 
proper way:

#if defined(ADMUX)
    ADMUX = (analog_reference << 6) | (pin & 0x07);
#endif


Also prefer original arduino here:

#if defined(ADCSRB) && defined(MUX5)
    // the MUX5 bit of ADCSRB selects whether we're reading from channels
    // 0 to 7 (MUX5 low) or 8 to 15 (MUX5 high).
    ADCSRB = (ADCSRB & ~(1 << MUX5)) | (((pin >> 3) & 0x01) << MUX5);
#endif

Works with another devices, not only 1280.
But i edited this way:

#if defined(ADCSRB) && defined(MUX5)
    // the MUX5 bit of ADCSRB selects whether we're reading from channels
    // 0 to 7 (MUX5 low) or 8 to 15 (MUX5 high).
    //ADCSRB = (ADCSRB & ~(1 << MUX5)) | (((pin >> 3) & 0x01) << MUX5);
    if( pin > 7 ) sbi(ADCSRB, MUX5);
    else          cbi(ADCSRB, MUX5);
#endif

Is easy to undertand, generates shorter & faster code.

Regards.
