You can purchase abroad and ship to your country. Amazon for example has country local stuff. Use the .xy for whichever country you want to search in (.com for US, .de for Germany, etc) and see if they have what you want.

You can of course read the code. The consequences are thus increased limitations, like you say.
What you mention is not an absolute restriction from reading copyrighted material. You perhaps have to cease other activities as a result.
Interestingly, this argument was also examined in a recent conference [1] and the same conclusions are drawn. Specifically: applications are using high-level frameworks more (and POSIX less) which use platform-specific extensions, ioctl dominates, and new (disjoint) abstractions are introduced by the major OS platforms.
