Protocol programming languages are domain-specific languages that offer higher-level abstractions for programming of synchronization and communication protocols among participants. However, most implementations of protocol programming languages on shared memory architectures use pointer passing to exchange data in communications, so programs can still run into data races. We report on our ongoing efforts toward the first shared memory implementation of a protocol programming language that
