I was just playing with my Titanium rssCloud app and having fun with the real-time effect of my test feed. i’m just using a webapp as a proxy to the cloud hubs so this subverts any firewall issues that have been mentioned. Now i’m looking at Entourage which is probably what I should focus on if i’m going to move forward with Titanium as framework for an rssCloud app.
Of particular interest in Entourage MQ:
Entourage MQ is a client-side message bus that enables many-to-many message pub-sub. It is seamlessly integrated with our Entourage Service Brokers to provide a powerful message-oriented client/server architecture, but it can also be used to easily consume any REST-based service.
