First let me say that I don't believe your own blog is a good place to ask a question but sod it.

What I want to know is if anyone has come up with an elegant way to take an existing ASP app and extend it using ASP.NET with a view to eventually replacing all the ASP pages with aspx ones?

Can the two separate tools be made to form one app seamlessley from the user point of view?

Oh I'm talking about a public website so anonymous authentication on the server.
