@James Mckenzie Fair enough, proper legal advice is needed. Can you give a link to the EULA about this point, or maybe vagelly when it says that. A web link would be nice. I think you are oversteting it, It sounds realy draconian, how do you distinguish between normal use of libraries, and this? If its really allowable under XP and not under 7, then it gets interesting. XP its still very whide spread, it could be tried with XP and earlier DLLs, meaning, if you have a legal liscence you do what the fuck you whant with them. It could be tried to make a hybrid wine/XP distribution, that is 100% compatible with current programms, and is incrementally "upgraded", by gradually removing m$ propety. The only chance here is that people start installing the hybrid on top of XP. And there's a reasonable chance of this happening with the help, of Mozilla, google and any company that has a grudge with m$. In general people are resistant to change, so maybe people them selves will prefer to hack there existing XP installation, in order to prolonge its life. This will get more important when suport for XP expires. If this gets traction, say for at least 20-30% of world users, software publishers, WILL follow suit. This should buy enough time, to allow for the entirety of XP to be cloned, whille its in normall use, not when its going to be deprecated.
