Can anyone point me to a modern example or description of using Asio with Spirit to parse and asynchronous stream. I keep finding articles that say this can't be done, or at least not easily (but the comments date back to 2007).

You can try coroutine. Here is an example of how to integrate coroutine with asio:

http://www.boost.org/doc/libs/1_54_0/libs/coroutine/doc/html/coroutine/intro...

I don't know how spirit works internaly - the example above could be useful if spirit reads from a stream (usually parsers read pattern from a continuous stream of characters). The idea is that the stream_buff used by the stream runs in a coroutine and suspends the corutine-context if not enough characters are available (from socket, in buffer). Another possible solution would be using the async_result feature from boost.asio (1.54) - but this depends how spirit works.
