Yep, but when this article was written, many online renderfarms were difficult to use, unreliable, or in some cases were using machines whose configurations were inadequate for even then. These days, there are cases when you need local systems doing the rendering and cases where using an online renderfarm is preferable. This article was published here on Tom's almost six years ago and the landscape has changed significantly since.
Heh I totally missed that it was old. I thought it was new yesterday.
