loadMovie

I am building a site for a friend. I have a movie that will look something like this

It is for an artist’s website so each section will be rich in content. I have been learning about loading external movies and thought this would be perfect. I could split the full site into smaller portions. Not only would it be easier to change on the fly (I would just have to update images on the smaller movies) but it would be more organized and much easier to manage.

I though I could load all movies (Part1, Part2, etc) into the MAIN movie (into separate movie clips) at the beginning and then display/use them as needed. But it appears you can only load into a movie clip that is currently on the stage at that momement.

I want to avoid loading each menu as needed. Since this site is for an artist there will be a lot of images. I would like to be preloading them as the viewer as looking at other things. I know this is what flash would do if it was all one movie (Streaming the data until fully loaded) but can it not do this with external movies as well?

So basically I need to know:
1.) Am I overestimating the ability of loadMovie.
2.) If not, how do I go about doing this
3.) If so, what would be the best way to do a project like this. I have read a lot about working with flash, but there doesnt seem to be much on the way to set up a large complicated move.

Any help or suggestions would be appreciated.

Thanks Jeff
