NetBeans Platform autoupdate via BitTorrent

Something I'm pursing nowadays is having my platform applications as decentralized as possible.

And the fist pet peewee I had is that fact that the Update Centers are such, big, centralized, monolithic blocks.

I always assumed that I would need to hack the AutoUpdate module from the NetBeans Platform quite hard in order to get what I wanted all along: BitTorrent downloads for new or updated modules.

So, the first thing we have to notice is that the AutoUpdate Catalog (see DTD) provides for each module in the Update Center a location called distribution. The distribution may be a relative path to the catalog location. That is usually something like ./com-example-mymodule.nbm or it can be a totally new URL.

Now we have a first step towards splitting traffic: we can put the actual NBM file on another URL altogether. Or, if we have the AutoUpdate Catalog location sit behind a servlet we could even try a bit of balancing and return a different distribution link depending on how loaded are…
