Hello. First of all thanks for your great book. Not really an issue, but just wanted a community place to air out a question. I know it's probably out of scope for your book, but do you have any guidance on a framework for integrating SSE with a live data feed? In other words, what would be the typical framework for obtaining the FX data that is simulated in the book?

Basically, it seems that the server-side SSE script is itself downstream from some datasource which could theoretically be anything: database, web service, etc., and that it would need to do all the things that SSE tries to avoid like polling.

In my particular instance, I control the datasource and I like working with PHP. But rather than go into ridiculous levels of detail about my own situation, I'm more looking for some pseudocode or library/framework recommendations so I can continue hacking. I've been toying around with PHP sockets, etc., but I'm not sure if I'm barking up the wrong tree or overlooking something very obvious.
