Considering the second precept
Adinnādānā veramaṇī sikkhāpadaṃ samādiyāmi.
which I am most familiar with its translation as
I undertake the training rule to abstain from taking what is not given
Does this precept only apply to cases of theft or can it be extended into more intangible possessions such as someones time or energy? Considering the answers around the illegal download question it does seem as if there are interpretation in which it is only theft. I'd particularly like to know interpretations from different schools and the differences (or not) between them.
For this can we take the definition of theft as provided by wikipedia
theft is the taking of another person's property without that person's permission or consent with the intent to deprive the rightful owner of it.
