I'm not a techie but I'm pretty sure if a pool wanted to mine just IXC they could.  Of course this would be an unbelievable feat since that would mean someone would knowingly not mine Bitcoin which would be a massive sacrifice for any pool.  The only way I can imagine this happening is if we could get someone to truly champion the iXCoin cause so much so that they would be willing to forfeit Bitcoin profits for the sake of making a statement.

Again, this is a highly unlikely scenario but it's something I would definitely envision and try and push for.
