Software matters because that is what determines things like how we want the wiki to behave.
The farm matters because that how the host's behavior is determined.
Do note, however, the two items are not mutually inclusive. With some farms they will let you run a different type of software than what they offer. Conversely, if you already have webserver space that has the bandwidth and services to properly accommodate a wiki, then it is simply a matter of acquiring the software and implementing it.
