Adrian,
We're always happy to try and split feeds when possible. We have several splits in the process, with a couple of MEGA splits coming for some major sites. Unfortunately these things cost money, though.
For reference, a 6 or 8 feed machine, complete with receivers, costs around $1200 to put together. Of course we can put something together on a smaller scale, say 2 or 3 receivers, but there's still a cost involved.
It's a popular feed, no question. If enough of it's listeners are willing to donate $30 - $50 a piece, we can split it out and make it yet another great feed.
