I really recommend this meeting as it’s a great chance to meeting an independent ActionScript expert from USA, ask advanced questions and so on.

Multicast Explained in Flash 10.1 P2P
July 1st, 2010
Multicast is one of the features of Flash Player 10.1 and it enables you to distribute NetStreams across the peer-to-peer mesh. It can be audio, video or even pure data stream (AMF3) - the data stream can be very handy for games, it’s much better for such purpose (like sending realtime positions, directions) than using Posting as Posting is more optimized for large number of senders to send something - like chat, status change and so on.
Difference between Unicast and Multicast
Unicast
Unicast simply delivers streams from a server to n clients. For this purpose you can use Flash Media Server and TCP protocols such as RTMP/T/S/E or HTTP protocol. Unicast also costs you a lot of resources -> 1 MBps stream delivered to 1000 clients means 1 GB upstream from server - which is CPU demanding and network transit is also huge.

Build An App In A Week - Recordings
P2P and LCCS
June 15th, 2010
Last week, my colleagues at Adobe and I organized an online event called Build An App In A Week.
The event was packed with resources for both RIA designers and developers and the goal was to build a complete full-featured app with various functionalities and challenges in just a week.
You can watch all the recordings here.
I was doing two of them - basically about developing multiuser apps, but the main goal was a chat feature inside the app.
One used pure P2P and Stratus, the other one used LiveCycle Collaboration Service. It’s not just a simple chat application; I also explain how you can build an Instant Messenger, User Lists, Private Messaging, and so on.
Directed Routing Explained in Flash 10.1 P2P
June 4th, 2010
Directed Routing enables you to send data to a specific client in the peer-to-peer group (NetGroup). It requires stable and correct topology to work well - still it’s very useful.
There has been already something written about directed routing. But I’d like to share with you much more.
First, let me explain you which methods does what. You have basically three main functions sendToNearest, sendToNeighbor and sendToAllNeighbors. See image below.
