Thomcult: Software piracy is a big issue, no question, but it is also a complicated one. There is a tendency amongst those who campaign against it to identify and associate it with other forms of piracy such as movies and music. However, the difference - and this is illustrated wonderfully by the R4 case - is that the skills required to pirate software are not in the least bit separate from those required to produce it.
The Nintendo DS has until now had a burgeoning homebrew scene, due in no small part to the proliferation of devices like the R4 that have allowed gamers to share and download amateur software. Furthermore, the relationship that has arisen between consumer and amateur developers has allowed for a greater degree of versatility and the production of many titles that Nintendo or its third-party counterparts may not have anticipated.
