Is there some method to create a transaction and make sure that it is the last in that block? If not, how close can you get to being last?
The reason I ask is that the following page depends on that being the case: https://github.com/slockit/dao/wiki/Why-The-Stalker-attack-is-a-non-issue
EDIT: By last in the block I mean that any transaction sent afterwards will be in the next block. Im not referring the ordering of transactions within a block.
