There's always a justification for an emulator beyond warez. Firefly is a developer himself, so I'm sure he's developing this to aid in homebrew development (remember his emulator for the GBA that came out before the GBA was even released? It only loaded small roms, cutting out the ability to run most commercial games. I'm sure the same will be done with his DS emulator).

Being a homebrew developer for several systems myself, I can tell you first hand that it's always easier to run code through an emulator than it is through hardware. With many emulators you also get the extra benefit of debug info (which you did with Firefly's GBA emu, so I'm sure the DS will be the same).
I personally don't see any problem with this emulator if it's done in the same way as his GBA emulator.
