IPage does not (currently) offer SSH access, so running CLI commands from a CLI seems like a lost cause.

In my test cases, I do use the Artisan calls which seem to call the CLI-equivalents (but throwing something like this up on a working site seems..... very unsafe)
Artisan::call('migrate');
Artisan::call('db:seed');
I've found that running 'php artisan optimize' on your local development box and then uploading the resulting site works fine. Even though your bootstrap/compiled.php will contain a few references to your local dev box, Laravel seems to work just fine.
If you're concerned about DB migrations, you can always pull the database over locally and run the migrations locally.
Not ideal, I know, but if you don't have extra-sensitive info, it can work.
