Hi All we looking to receive external trxs before they go through the dropping or acceptance logic of a node and being added to the transaction queue - https://wiki.parity.io/Transactions-Queue - the aim is to catch any double spend attempts -is this something we could subscribe to through Infura - essentially listing to trx messages on the Wire Protocol Devp2p https://github.com/ethereum/devp2p/blob/master/caps/eth.md#transactions-0x02 or possibly there is a library for us to use to access this protocol

Hi @Daniel_Lipshitz. It sounds like you just want raw access to the devp2p wire protocol data. I would recommend taking a look at https://github.com/ethereumjs/ethereumjs-devp2p specifically their example apps in https://github.com/ethereumjs/ethereumjs-devp2p/tree/master/examples.

It should be relatively straightforward for you to add custom event/logging hooks to the new transaction events that are received over the p2p network.
