Take long time is relative,you usually have some Error Message and/or
File/Registry access calls, you can certainly obfuscate the routine, but
that won't delay it forever.
Key generators are not the only solution, patching the whole routine might
be possible too.
As for references, i guess you should read both sides of the story, search
for papers from companies who write copy protections and the appropriate
countermeasures from crackers. There is too much useless stuff writte about
this topic. Can't help you more...
