@azizur

For every:

add_action('init', 'oauth_init');

You are potentially calling flush_rewrite_rules();

This could cause performance issue.

Instead call flush_rewrite_rules(); on plugin activate and deactivate action hook.

See: http://codex.wordpress.org/Function_Reference/register_activation_hook for more info.

@ozh

This is a nice example of the rewrite API, but by no means it is an "oauth script"...

Well, azizur. looks like i've fixed that already.
when you activate your plugin, you just need to set $oauth_activate to true on activation.

as for deactivation, i think we shouldn't remove the rule as some other plugins may want to use it, anyway i guess user will get a 404 error page on "/oauth/" if the OAuth plugin is deactivated, right?
