Seems like Kevin Lynch’s comments don’t exactly jibe with yours:

It sounds in his interview that the point of P2p is to lower video costs. What’s the deal exactly?

Will a flash player be allowed to have multiple connections to multiple different parties at the same time?

Cheers.

It’s great support.
What I think is: why we can’t use USB-PHONE with Flash Player ?

We only take an USBPHONE like “microphone” but we can’t send audio-output in different device !

Flash.Sound.setAudioOutput(1); // usb phone
Flash.Sound.setAudioOutput(0); // speaker of pc

I think that have no-sense to build very amouth of tecnology, without native speaker-selector support…

I wonder if RTMFP was changed by Adobe after Amicima MFP.. looks like there are some licensing issues also, which will be hidden from the world as MFP was an opensource project with GPL license

[...] Justin Everett-Church recently released some new details about the new RTMFP protocol that will be available with Flash Player 10. RTMFP stands for Real Time Media Flow Protocol and is going to be used to leverage the new peer to peer capabilities of Flash Player 10. The communication between peers is going to be managed by a future Adobe server technology (Flash Media Server 4.0???) which will keep a list of peers that can be connected to. If one peer want to connect to another, the server translates the peer IDs to network addresses, and assists in setting up the connection if one or both ends is behind a Network Address Translation (NAT) device. RTMFP is a UDP-based protocol and packets are sent directly from one Flash Player to another. If UDP is blocked by a firewall or if RTMFP is blocked through a configuration of mms.cfg, the peer connection will not go through. [...]

@wes The fascinating thing to me about that question is how few people know the answer. I don’t know, and I don’t think you know either (no offence intended — being honest). I’m not even sure Justin knows, and he’s on the Flash team.

The reason so few people know is the intersection of skills it takes to pull off. First, you have to know the p2p side. That cuts out 99+% of developers. When I say “know” I basically mean you’ve coded p2p apps. Then you really, really have to know the ActionScript API, and there are gems in there that aren’t obvious at first. The combination of those two leaves very few people who can truly answer that question, and it’s part of the reason for the flailing in the blogosphere.

Stepping back, though, that’s the cool thing about platforms — they’re largely only limited by the creativity of developers. This will certainly get interesting.

Justin,

Thank you for clarifying and giving us a definite answer.

Two weeks ago I sent email to fmsprerelease@adobe.com to be considered for the RTMFP beta programs but haven’t heard from Adobe. We are very interested. Is there something else we can do to be considered for the beta program other than just sending email?

Here’s another question for your FAQ (I know the answer, but people don’t believe me when I say it):

Can Flash Player 10 be used to swarm video to reduce bandwidth costs?

Very Powerful! It can effectively reduce pressure on server, as it doesn’t need to pass the data through the server. If the flash video player 10 can reach a higher level, it would be very easy to own a video-share website without high-tech as long as have a system built successifuly. It’s meaningful for high traffic video-share site like Youtube!

Philip, It is still P2P communication in that the two Flash Player clients are communicating directly without passing their data through the server. It is however a managed connection in that the server does the introductions and you must still be connected to the server to retain your P2P connection. This is very similar to many IM client models where P2P communication is allowed in the context of still being signed in to the IM service.

ByteBuffer, there is no support for UDP over the socket object in this release of Flash Player.
