A +total crash would be considered very serious - 1 BTC - while excess +bandwidth usage would be considered minor - more like 0.1 BTC.

Adding a new test that demos your exploit to the unit +tests will be looked upon favorably.

I've got a bit over 2BTC budgetted for this, which is +coming out of my own pockets - I'm not rich!
