Pheace: If anything it seems like a good opportunity to start selling T-shirts in the store xD
real.geizterfahr: Shirts are gonna be DRM free but washing them will only be possible in Galaxy...
I mean, by the time the shirt got out of the Milky Way in order to check if it's possible to wash it outside the galaxy, washing it will likely be among the last of the questions around it.
Either we have an object able to travel at the scientifically measured speed of fuckthatsfast (a few times light speed, roughly), humanity's long since dead (how the fuck have the shirt survived for ashittonyears?), or the shirt have long since disintegrated and thus not been able to make the journey to the washing machine anyway.
