Help is needed!

For the NetStream loader it doesn't have the optimal solution it first save the file to local >disc and then play. t will be perfect if it could buffer the stream and in end create file out of >it.

It is what I do in one of my demo project using Thread to download files concurrently.

I use an URLStream to download internet files and each 0.5s, I write in a FileStream what there's is in the content loader using a ByteArray buffer, even if the user pause and terminate the Thread and restart the download again, what I do is I restart the download from the cache, I check first the file size didn't change on the server, if it has changed (could happen), I start the download again but from scratch, to know if the size of the of file has changed on the server I use SQLite to store the info.

You can have a look at the Runnable (a bit the same than a Worker but managed by a Thread and created in-memory): https://github.com/doublefx/easyWorker/blob/master/moreFlexDemo/downloadFileThread-Demo/src/infrastructure/thread/impl/DownloadFileRunnable.as

I hope it will help you to achieve your goal but if you have any question about the implementation, just ask.

I suppose it might be useful to share potential use cases (I guess there is such thing as "use case driven development").

You have AIR app, desktop or mobile – doesn't matter, but think of it as an app for exhibition. It is data driven and that data comes from server (usually it's editable by some sort of CMS). So you want to pre-cache all the assets first on the startup, then start the app.

I can imagine, it is possible to do with the current version (simply by loading every asset). But there is really no point to use actual loader classes – it would be better to download them via Loader.loadBytes() and directly put the into storage directory.
