Since
Ercoin is going to be distributed via BlackCoin burning, it would be interesting to know the date of the blockchain snapshot for the purpose of BlackNet distribution. If it happens during the burning period, then the two will interfere.
I see two possible outcomes:
1 BlackCoin = 1 Blacknet + 1 Ercoin
1 BlackCoin = 1 Blacknet or 1 Ercoin
In which one are you interested?
I would prefer NOT to see a reduction in the overall supply of Blacknet, therefore Blacknet snapshot before Ercoin/Blackcoin "swap and burn" opportunity.
"1 BlackCoin = 1 Blacknet + 1 Ercoin"
It's assumed here I think that Blackcoin won't need to be burned to receive Blacknet tokens.
