WebDAV support was our highest priority for syncing because many people need to be able to sync between remote locations that cannot directly talk to each other, and WebDAV (which is actually what we use for the iDisk syncing as well) provides a solution for those people as well as for people whose machines & devices can communicate directly.

Having said that, we would like to provide a solution that doesn't require people to purchase a WebDAV account. I can't make specific promises or give a time frame, but it's certainly something we're exploring.
