Sharing data between native and webapp

[beer2]

Hi!
I've been looking for this info for some time, and seem just to turn in round..
What i would need to do, is to share some data between a native objective-c application, and a webkit javascript application... Do you have some ideas how this could be done?

I was thinking of sqlite databases, but according to the documentation, an application can just write/read files inside its own directory... So i guess it couldn't have access to the webkit databases (under ~/Library/WebKit/Databases).. (and the other way either).. right?

Can you think of a way to make this work? Or another trail I could explore?

Thanks in advance!
