A lot of people attack the SFC for being too aggressive, but it wasn't until the SFC started an aggressive campaign, using Busybox as a weapon (around 2006/2007), that as a consumer I started seeing devices released with little GPL leaflets and the source code available for download.
I don't know if any of the devices I've seen were as a result of direct action against the vendor, but the actions of the SFC, FSF and others surely helped encourage vendors to comply.
Now for a bad analogy: If a Sony caught somebody downloading one track, I'm sure they would insist on checking everything else the copyright violator owned for further violations and the SFC's aggressive litigation demanding to review other products for more GPL'd code is no worse. Only in this case the defendant's tend to be large corporations who can afford to go the distance instead of college kids and grandmothers!
P.S I know you are suggesting the project outside of your work for Sony but surely you can't expect to take the moral high ground against the SFC while working for such a litigious and ethically bankrupt company.
