There is nothing wrong with swapping links like that. It just becomes a problem when you automate it. People used to create directories on their website and swap links with anybody that would do it. There is a huge chasm between swapping links and putting up a directory. If you have to put up special software to swap links your in the wrong. If your goal is to try and find the exact line between the two practices your also wrong. Do what comes natural it is ok.
