A feature request for WebSocket support has been added to the Community:

http://support.cloudfoundry.com/entries/20810903-websocket-support

Technical concerns raised so far:

1. The backbone of the Cloud Foundry router implementation (nginx) doesn't yet support WebSockets. This needs to be added to nginx or a new Cloud Foundry component is required that handles routing of incoming WebSocket connections.

2. The number of concurrent connections a WebSocket router can maintain to an app instance is limited to the ephemeral port range (65,535).

3. Given that WebSocket connections are inherently long-lived, exhaustion of kernel resources or degraded performance of apps on a Droplet Execution Agent could occur.
