walkah: Nokia n91 + OS X Address book anyone?

OK. This might seem silly, but I *really* want my n91 to pair with the Mac OS X address book. Why? Because this would allow me to send and receive SMS messages without picking up my phone, as well as making calls. Trust me, it's a nice feature - especially since the n91 has a nice charging cradle where I could just set it and leave it. Sadly, it appears it just doesn't work.

It looks like these Address Book Phone Plugins from Nova Media claim to fix the problem. However, they want my hard earned money before I can even try to see if it works with my phone. Can anyone confirm that they work with the n91? Or should I just wing it? Are there other options?
