And if not could someone give to a link to a tool that can burn a bootloader to atmega 2560?

Does that definitely handle the +64Kb memory boundary?

As they name the product "USBtinyISP" I suspect it suffers the same +64KW (not bytes) limitation that adafruit's USBtiny programmer does. However that is just logical speculation on my part.

I stand corrected. The limitation is at 128 Kb which of course affects the Atmega2560. This is because you program the flash in words, and at the boundary of 64 K words (128 Kb) the extra instruction "load extended address byte" needs to be sent to the processor.
