There is a node that will always relay every transaction, regardless of whether its amount is acceptable and whether a fee was paid. This node is described in the Free Transaction Relay Policy page on the Bitcoin wiki.
There are no miners listed though which will always include these transaction.
Microtransactions for amounts worth just a few cents would not be able to pay a fee and even the minimum fee causes Bitcoin to no longer be "near free", as the amount on a percentage basis can become quite high.
Are there any miners which will include these microtransactions with no fee? Do any of them connect to the node listed in the free relay policy page, or are the IP addresses for these shown anywhere?
