A system and method are provided for supporting remote isochronous devices effectively. In one embodiment, first and second computer hosts include first and second virtual interposer logic, first and second send/receive logic and first and second at least partial device driver stacks therein. The first and second send/receive logics are configured to communicate packets between one another, representing commands and data passing between a user-level application at the first host and a peripheral device at the second host. The first and second virtual interposer logics are configured to interface the first and second send/receive logics to the first and second at least partial device driver stacks within their respective hosts. To achieve low-latency transactions, the system includes speculative write completion functionality and/or speculative read functionality.
