Re: [Playerstage-developers] Preparing for Player 2.1 release

[Radu B. R. <ru...@cs...>]

Good point. Well, what about transport mechanisms ? (one of the few remaining "issues" - 
if we could call them that way - that drove people from Player away)

Let's see... it seems that one of the most popular ones is ICE right now. So the solution 
would be to create a libplayerice and have it as a transport option instead of the 
classical TCP/UDP. However, some problems that will arise here:
- ICE does not have implementations for every programming language, so a lot of clients 
will not work. Therefore, we need to make sure that ICE is an add-on not a replacement for 
TCP/UDP
- client libraries will have to be modified, and we need a way of "knowing" what transport 
mechanism is used, although we could just leave that to the user
- I have no idea whether ICE works with embedded systems (eg. Gumstix)
- ... anything else?

One nice thing that YARP has is that you can switch between TCP, UDP, shared memory or 
multicast rather easily (with the use of ACE).

Cheers,
Radu.
