Put the plugin in the wp-content/mu-plugins directory. Each site in your network has its own _options table in the database so as long as you are using built-in WP functions for handling your plugin’s options, each site will have its own distinct set of options.
When referring to urls within the network-admin, you should consider the network_admin_url(). core function, that falls back to admin_url() for non-multisite setups. So try this, using add_query_arg just as @toscho uses in the answer OP links to: echo esc_url( add_query_arg( ‘action’, ‘your_option_name’, network_admin_url( ‘edit.php’ ) ) ); instead of hard-coding it with possible wrong assumptions … Read more

The plugins folder is shared. You can install one copy of the plugin and activate it on three blogs and not the others. If you don;t want the others to be aware of the plugin’s existence… you’ll have to use another plugin to exclude it. http://wordpress.org/extend/plugins/restrict-multisite-plugins/ or http://wordpress.org/extend/plugins/exclude-plugins/

During the load process, WP loads wp-settings.php, which calls is_multsite(), which checks for the multisite constant defined in wp-config.php if it is a multisite install. If it is multisite, then ms-settings.php is loaded. Inside ms-settings.php, WordPress parses the requested URI to get the domain, and calls wpmu_current_site() to set all of the current site constants … Read more
