challenges of round doors

[cellio]

There is, apparently, a construction company out there that will build you a house styled on a Hobbit hole. Naturally, an important question arises for Jewish owners of such homes: do you put a mezuzah on a round door, and if so where? The mezuzah is the scroll (containing certain torah passages) in a case that is affixed to your doorpost -- so what exactly is a doorpost?

A round door still has to open and close, right? Hobbit hole doors as seen in The Movies opened iike rectangular doors do, so they had doorposts, just short ones.

Now, how do these nice people construct their hobbit hole doors? *goes to look*
