Suggestion: when mining is BN only, can all tx fees get added to the asset backing?
Reasoning: individual BN ops aren't going to be greatly affected, they are already paid their share of the block reward, but a steady trickle of fees over time will help the currency's backed %, making it that bit more appealing to investors.
I don't know if this would complicate what's currently being worked on, and it's not anything urgent, just a suggestion for some time in the future maybe.
On the subject of BN reward though, since BNs will in future be using presumably ~100x more CPU each, is there a case for upping the BN % a little to cover running costs? Running multiple BNs on $2/month VPS instances is no longer going to be an option.
