Either...
1 - nobody has done this
2 - nobody knows what I am asking.... :-)

number 2

Thought so! :-)

None of both; it's option 3 (I'll explain later).

At least I know what you're talking about, and I've done it; my databases are InnoDB. Also because I have the database running on a stretched Percona cluster, so you can't put it into ISAM.

The reason it's not done regularly is that most users of RadioDJ use the database as a local install on their playout system, and the benefits of InnoDB are on systems with the surplus on capacity that normal computers have these days not really notable.

However, it differs a fraction, and if you're in for it, you can use it.
