iPhone Notifications

Hello,

So I wanted to setup a way so that I get a notification on my iPhone every time someone logs into a WPMU website. Pretty neat idea.

http://pushme.to/ is a free iphone app. You can send notifications using PHP.

This website contains the PHP code requires to send a notification using pushme.to:

It consists of two parts:

1) function pushMeTo($widgeturl,$text,$signature) {
[snip]
}

2) pushmeTo ($url,"Hello Hello!","Your Bot");

I successfully setup a test using a plain php file which sends a message to me iphone. Neat.

What I need some guidance on is how to ingrate this into Wordpress's admin login form? Any ideas?

Thanks!
