Approve/Reject in email generated by SharePoint

sharepoint outlook workflow acceptbutton

When I make a meeting in Outlook, the recipient gets a approve/reject button in the top of the email. I'd like to do a similar thing with SharePoint: when a task is created, an email is sent to the person the task is assigned to, and the email asks the recipient to either accept or reject the task. I've seen demos of people doing this with a custom ASPx page, but I'd like to make it directly in the email. How should I go about doing that?

I'm used to making workflows in Visual Studio, so I'm happy with code examples for setting up an email and/or parsing the response

Cheers

Nik

The approve/reject buttons in Outlook shows up because the email is in the iCalendar format. I dont know if this is the best way, but you can send out your own iCalendar emails using C# code and set the response email to a mail server you control. From that mail server you can process the email and use the SharePoint WebService API to approve the item in SharePoint.
