Beyond the expenses of hosting such a server (especially if it became popular)… I like this idea. And I’d pick to keep it simple, 100% automated station, user submitted mixes. Maybe make each day have a theme: house, techno, dubstep, breaks, dnb, hiphop, etc.
why not go for djtt.tv instead? It could be a place for Ean and co do their videos live (what happened to that idea btw?) and also for dj’s to stream webcams in the studio or at live gigs.
There are plenty of dj’s on here - I’m sure it wouldn’t be difficult finding people to play. Difficulty is funding I’d imagine…
