There is no "licensing" for Tiger... or for any of the past OS's 😉
There is a "registration" but you can "skip" that if you really want to.
There IS licensing, meaning that you agree to only install the OS on as many machines as you paid to have a license for. You may reinstall the OS on hundreds of machines, as long as you first delete it from the previous machines first and only run and have installed one copy of the OS at a time (or more for a multiple-use license).
That said, there is nothing in the Mac world to physically stop you from buying 3 computers, one copy of Tiger, and installing that one copy on all three computers. You simply are using pirated software at that point.
SIDE RANT: Almost everybody uses SOME level of software piracy (I think). It simply depends on your moral fiber as to which level you are willing to go. Of course it is wrong and you should not do it, but I admit that even though I am pretty adamant about not stealing software, I DO have a few songs I downloaded off a peer-to-peer (that were not otherwise legally available other than by purchasing a whole CD at $13-18 for one song). I consider them loaners, meaning that I WILL pay for them when they become available on iTunes (and I have later paid for many songs in that very boat). I also have used some shareware programs too long without paying (almost always because I did not really want the program and did not find it worth the cost and I only needed it a few times several months or years apart--but I also have many, many shareware programs that I DO own legally (Solitaire Till Dawn X, WindowShade X, ASM, RadioLover, GraphicConverter, etc, etc, etc)) So yes, pirating is wrong, but very few of us have PERFECTLY clean computers.
