Using to sync your phone with Outlook

In a comment on my blog entry Mobile phone backup with ZYB#c707, John pointed to a tutorial on how to use as a kind of middleware for syncing Outlook and your mobile phone.

The idea behind TechTag's How to easily sync Outlook calendar with an ordinary cell phone if you can use the ZYB service not only as a backup facility but also as a "shared storage" to keep two phones in sync, why shouldn't it be possible to sync your phone with your Outlook calendar and contacts via ZYB?

The only problem is how to connect Outlook with ZYB. TechTag tried two different SyncML plugins for Outlook, having more success with the non-free one.
