Does this work with a modern Windows like W7? Anyone know.... 
pc2amiga is best solution, way better than Amiga Explorer. but, IIRC it wouldn't work in windowsXP, let alone win7. perhaps it might work in some compatibility mode, or in win98 with virtualbox.
you can get excellent speeds with (custom) parallel cable. just make sure pinout is correct and keep in mind that some cable versions are not 'symmetrical'
oh, and it requires KS2+
