You might have some luck using pipe and setting the chunk size to 1? That might be slow enough that it doesn't fill up the output stream - but it's not very efficient. You're probably better off manually reading from the file and outputting via an interval.
We were considering putting another MCU (eg. STM32F030) for this kind of stuff...
There's always the upcoming Espruino WiFi board :)
