What is the reason? An install script? If so, there are probably better options for you.
If you do need to go down the route of Artisan, then you could take a look at the SSH options Laravel has out of the box.
http://laravel.com/docs/4.2/ssh
You can basically connect to the server (Or remote server) and run shell commands. That should work for you I guess.
I haven't heard about running commands in any other way. I could be wrong and would love to hear otherwise. The SSH option would work for you though in the meantime.
Hope it helps.
and i found that also
Laravel 4 have a lot of features some hidden :) for some developers, i found the option to run artisan commands from route or controller, like Artisan::call('migrate:install'); or Artisan::call('migrate', [ '--path'=>'app/database/migrations' ]); Artisan::call('db:seed'); it is usefull when you don't have access to the console in share hosting environments.
