Pros and cons of using BlazeDS or web services as the remoting and messaging technology between Flex view layer and Spring business layer?

In my company, we are going to use Flex3 for the presentation layer of a new financial web application and Spring for the business layer but a debate is still going on regarding the best messaging/remoting technology. Can you share your own experiences in terms of pros and cons of using one or the other technology?

If you're recording video, you either want to stream it in real time (look at RTSP protocol that the high-end IP cameras use, implementations can be found in gstreamer or vlc), or if you're pulling the video after its been recorded as a file then just use a normal web upload system.

Chances are your camera that records the video could be sending the data feed as RTSP anyway, so you might just need to connect to that feed.

I would use a web protocols these days anyway, no need to reinvent the wheel. There are many webservers for embedded systems (open source civetweb comes to mind as something very simple and effective). Then you're creating your program using established, common web services. Easy to build and well understood by practically everyone.

WS-* protocols are complex, if you can't get a lib working, then it might be a lot less painful just to register a server service in the network's DNS and let each client tell it (via a REST API call)) what its current IP address is. It would be even easier to have each device be registered with the networks' DNS server from the start though, to discover which are available you just need to ping each one then.
