[LAD] Four decks audio player for radio stations

I was recently helping a small Dutch radio station run by volunteers to
set up their new studio.

It's a modular system with a 16 I/O firewire card:


We managed to support it in FFADO. The playback software runs on a
virtualised Windows machine that's talking to jackd via netjack (no idea
which one, the one with multicast and netmanager), so we can address
four individual stereo pairs.

This whole netjack thing isn't very stable, so the playback software
should be replaced by some native Linux client. Here's a screenshot of
the current Windows solution:


It is basically a set of four remotely controlled winamps (with ASIO
output plugin to talk to jackd) and a directory browser per player.
So "Jingles", "Muziek" and "Bladeren" are just shortcuts to directories
with media files, the drop-down menu on the left contains a list of even
more directories.

The filter is used for pattern matching.

Questions: Are you aware of any Linux solution that comes close to this?
If not, any recommendations if one would want to create such a four-deck
player? Leveraging VLC, mplayer, gstreamer?

This is surely going to be open source, so whoever is interested, feel
free to participate.
