GPL versions not such a big deal

In the combined work, yes, but in your code, no. You granted the permission to tivoize 
your code, your permission is there, latent. If I take _your_ code and put in my TiVoSX, but 
not the code that the other author does not want tivoized, it's ok. That is the beauty of the 
GPLv3+waivers:

Your code: GPLv3 + waiver tivoizing
My code: GPLv3
Combined code: GPLv3

If anyone wants to tivoize your code, _nothing_ will stop them. Your wishes regarding 
_your_ code are _always_ respected. Now, your wishes regarding _my_ code...
