Open source app for remote wiping Android phone? I recently lost my android phone, and regretted not having a remote wipe app installed. However, I do not trust 3rd party compiled apps with such power (too many weak links).

Does anyone know of an existing open source app to do a remote wipe?
For non-rooted phones. 
Up until 2.1 it is not possible. Regular apps do not have the permission to perform full wipes or factory restores. I believe there are apps that erase your call/sms records and your contacts.
Starting with 2.2, it seems Google is granting limited root powers to apps that use Device Administration. It is supposedly a way for enterprises to policy their employee's phones, and requires an extra confirmation by the owner. But I believe it could be used by anyone writing an app. In fact, the code for wiping seems so simple that I think you could write an open-source app yourself if you have some programming background. ;-)

For rooted phones. 
There are remote wipe apps, but I don't believe any of them is open source (that I've heard of).
Remote Wipe for root users is possibly the simplest one, and it's in the market, but I've never tried it myself. This app is no longer on the market.
