Would it be possible to change the Template.Update and Template.Create methods to also accept a form post or byte stream of the new HTML and Zip file?
I'm auto generating new templates based on user input(mainly generating html tables from excel and then adding the table to an existing template). Testing this is impossible for me without deploying my code to a publicly visible web server. Needles to say this is very time consuming and difficult to debug.
This hasn't been requested before, but I can understand how it would be very useful in certain cases. I've added your vote in our internal suggestion tracker.
