Can someone clarify something for me? How much bandwidth does running a node generally eat up per day?
The only thing that uses any bandwidth worth considering is the Bitcoin node. If a new node pulls the Blockchain down from your node thats 20gb (uploaded from you).
Other than that is kb/s for transaction traffic.
And your p2pool node
pooling pulling down shares.
It may not seem like it is much ... but the other day I had to kill my local node because it was saturating my limited bandwidth (3mb/s down). It wasn't bitcoin, it was p2pool. And it was long after I'd downloaded the chain (I'd been running for days already).
