The DroboApp version of the latest minidlna is available for download:
As usual, you can find complete step-by-step instructions to compile it from scratch if you feel inclined to.
This version includes an user-provided patch to support several instances running in parallel , which means you run two instances on the FS: one with everything you have, and one specifically for your kids.
Forum user sshambar  created another patch that adds a bunch of other stuff to minidlna , but since I could not really dissect everything he did, I decided not to include in this version. If anyone is interested I can make another version including his patch, but like I said, I’m not sure how stable it is.
