Since I joined the modern wireless generation by buying a Sony Ericsson T616 last December, I’ve discovered the joy and pain of keeping my address book synchronized.

It’s more of a pain than a joy sometimes.

Here’s the problem: I want to effortlessly synchronize Thunderbird on three machines, Outlook, and the Mac OS X Address Book, with my mobile phone.

In short, it’s just not gonna happen without some hacking.

But this problem got me to thinking. What’s the one thing all these platforms have in common?

What’s common is what I have in my pocket whenever I use any of my three systems: a BlueTooth-equipped mobile phone.

I think what should happen is that rather than manually synchronizing 5 different address books, each mail application should reach out and query my Bluetooth device in real time.

I don’t know enough about wireless technology to know what would be necessary to make this happen, but I really want it.

Have you ever wished for ubiquitous directory services?
