Answer 1

Generally the best communication technology between flash/flex and a server is the Adobe Message Format. AMF is a communications specification created by adobe specifically for this purpose. In ruby you can use the open source RubyAMF.

a good tutorial for all of this can be found at : http://natureandtech.blogspot.com/2007/10/beginners-tutorial-to-rubyamf-with.html

its really quite simple and fast once you get the hang of it.

See Greg's answer for a good option. In my case, I preferred to use a JSON interface between client and server so that any client can access the same server as long as it's capable of processing JSON.

To do this, we just use standard REST (just GET/POST ) calls via HTTPRequest on the Flex side. The URL is typical: /controller/function/id.js ("js" to tell it to use JSON format). You might to to add a JSON gem to your ruby install.

This keeps the API simple and portable, but I'm told AMF is faster.
