All I found was an old thread that was 4 years old..
But I am wondering if there is any continued effort (or revisiting the effort) to run zenphoto with sqlite.
My server had a filesystem crash 2 days ago; and it's been a while between backups; and so now I will be spending the next few days "trying" to recover stuff out of mysql. The old HD is still intact, and if zenphoto was running sqlite, then I would have been able to just cp -p * and all would be well. Instead, I have to muck and try to get mysql to cough up some sort of backup.
So again, I'm hoping to generate renewed interest in sqlite.
