(Idea) Offline Instructables Editor/maker

So I have had this idea in my head for some time now, and I finally went and tried it out. I'm always mad when I can't work on a instructable because the computer doesn't have internet, so i decided to try and make a editor that would edit and make instructable offline. I figure that i would gets this idea out in the open before going further because it does need some help from everyone here. I already thought up a way to make a type of file format. I took a zip file, put all the instructable files into it, and then renamed it a .ible file so it stands out as a instructable file. i have attached the test .ible fine on the forum so you can take a look at it(just rename it .zip to view it for now). i have a main config fine called CONFIG.instructable which contains all the basic things that it would need to know about the instructable. it tells it the title of the instructable, where to find the text for the intro, the pics for the intro, and then how many steps. there are then config files for each step. the names are simple, step1.config. in that it tells it the name of the step, what the name of the body text file is, and then how many pics are in it and the file names of them the thing is, this file means nothing if we can work out some way to upload it to instructables in a way that it is recognized as a instructable and loaded correctly. I figure that before I go and try to make a program that will make these files, I should ask if this is even possible. So what do you thinl?
