Warning! Geeky content within. Those of you who know what VLANs are are probably interested in this article. In the past, Apple only supported VLANs (802.1q) when using OS X Server. It wasn't a huge deal, as servers are much more likely to need this than clients, but it is an important feature nonetheless, especially for those of us who do weird networking things.
Big wins all around for the networking crowd.
