As far as i know you can set for every map in the mapcycle one single download location. So
train_gamma can be loaded from SKracht's websapce, and
sliema from Samtron's websapce and so on... This would not work as load balancer, but it distributes the traffic and prevents dswp server from bandwith problems, so that massive downloading does not disturb the gameserver (I think SvaRoX mentioned this problem sometimes).
I have also fast university websapce, but I don't want to risk any account disabling. But I can offer my normal webspace, enough space for a map and ~ 24 GB traffic per month (I don't know if this is enough for one map in one month). But SKracht can host every map, when he has no limitations ...
