I had a client who had a forum which sent emails based on cron jobs.
They moved to a host which didn't allow cron jobs and tried your
suggestion. Too many messages got delayed for too long - for instance,
a thunderstorm knocked out power to their office on a Friday evening.
No one was in there to restart the system making the calls until Monday
morning. Meanwhile, all kinds of messages got lost.

It's not bad if you want to do stats; miss a day and it will still
recover the next day. But people who want *reliable* results know
better. And if you don't care about that, why not just host from your
house? It's much cheaper.

I am in the game here. First of all, you cannot modify php.ini unless
you have access to the system - in which case you will have no problem
setting up a cron job. And many (most?) shared hosts do not allow the
max_execution_time to be overridden - for very good reason (reliable
hosts won't, at least).

As for crashes - all kinds of things can happen. The script itself can
crash; systems do get rebooted. And how are you going to restart the
script without access to the system?

You show an amazing lack of practical knowledge of how hosting works.
