Hi, Magnus,

AFAICS from the FAQ http://www.sqlite.org/faq.html#q7 and #q8, SQLite
does serialize itsself.

Okay, I understand, but I hesitate to endorse it.

IMHO, they should write their application in a "normal" way, and then
have the serialization etc. encapsulated in the database driver
interface (possibly a wrapper class or so).

Well, most of those projects don't need a database, they need a bunch of
tables and a lock.

Heck, they even use client-side SELECT-loops in PHP instead of a JOIN
because "I always confuse left and right".
