Solving that problem is pretty easy actually: just add a voting only
public key to your outputs. Specifically you would have an opcode called
something like "OP_VOTE" and put a code-path in your script that only
executes for that specific key.

It'd work best if we implement merklized abstract syntax trees to allow
you to reveal only the part of a script that is actually executed rather
than the whole script, a feature useful for a lot of other things.


Incidentally remember that we can implement as many new opcodes as we
want with a soft-fork by redefining one of the OP_NOP's to be a
OP_VERSION opcode that returns false for a given version:

version OP_VERSION OP_IFNOT {new opcodes} OP_ENDIF

Nodes with the existing codebase will think the script always succeeds,
because the IFNOT branch isn't taken, leaving the non-false version on
the stack, while new nodes will take that branch.
