All of this also pre-supposes that the phone is somewhere that gps can actually function. You might also consider using cell tower location (i can't remember what its called) to at least get a general area. I saw a demo of this concept in the moble google maps application.
Another way to prevent your secret data from being stolen off the phone would be to implement something like a web services based storage provider. The os could use it like a relatively slow file sytem, over an encrypted link and cache it locally and temporarily. Have it sync periodically and auto wipe if the wrong password is entered at boot or waking up from sleep / etc. No loss of data except what may have been changed since the last sync before you lost it. Shouldn't be that hard to implement. Obviously its not for everyone, lack of a flat rate or 'unlimited' plan would make it unsuitable. There is probably no universal solution.

It's certainly prudent to realise that this is far from a full-proof
phone theft prevention system. I realise it's a little redundant to say
"aaw, but no security is airtight anyway!", but it's worth pointing out
Encrypted data, a device that phones home... these are all flawed but
noticeable barriers for the potential thief. It is also worth noting
that the data stored on a phone like the Moko (emails, passwords, ssh
keys) is significantly more valuable than the type of data stored on
ordinary cellphones at the moment ("hey, how r u? <3" x 500, some
pictures of people being hit by bins) so it is more important that the
owners of the devices, and the developers, think more seriously about
how to protect the valuable data that is being stored.
The Moko has the hardware and the flexibility, so I doubt it would be a
great deal of trouble to implement a little GPS app that phones home
when it gets lost.
My main point: the system may also be useful if the user has simply
misplaced the phone and would like to find out if they've left it at a
friend's house or at the pub. GPS is getting accurate enough to
determine which area of the house it is in. It could eliminate the
possibility of it being stolen if it turns up in a familiar location.
How is the Moko user going to tell if they have dropped their phone on
the train and it is sitting unclaimed at the lost & found depot of the
train station? GPS, of course :)
