Do you plan an IE7 SDK?

Hi,

I'm completely new to the IE7 world: I've never developed an extension even for IE6, and I thought that with the arrival of IE7 someone would have proposed a toolkit in order to make it easier to develop a plugin for IE7 (let's say, the same way there is Visual Studio Tools for Office,which I'm pretty happy to use!)...but all the information I've found let me think that the Object Model is the same of IE6, and there'll be no professional tool for users :(.

Could you give me a complete order list of what I should do in order to develop a fully functional add-in for IE7/IE6 At the moment (but I had found it some months ago) I've read the CodeProject tutorial...what I'd like to know, for example, is how to build a secure and efficient installer (the same problem I had got with my plugin for Outlook...)

Thank you very much!!
