Vista - WCF P2P beginner questions

Hi,
I consider if to implement p2p application over WCF.
before I'm begining I want to know:

1. Can I make direct conneciton using WCF between 2 peers behind different
NAT's / Firewall ? , Did WCF make the all connection transparently , or the developer should also code some part (connection issues) , is it use Hole punching do make direct connections between the 2 peers when possible , or , use every time some intermediate server or node that is not behind NAT ? , the developer have control over the life time of the connection like using keepalive in socket programing ?

I read in some place that the end user should open ports etc and enable pnrp , there is a way for the developer to make all this via installation or other "silent and simple" approach ?

2. even when using Binary encoding , is it still send bigger data then using sockets ? , there are some numbers or statistics about it when sending large amount of data. ?

3. What Os versions support WCF , Is WCF will be supported under Mac /
Linux in the future ? there is some evaluation date for that ?

4. Installing net 3.0 / WCF can harm my current working VS 2005 solution (winxp sp2) ?
should I migrate it from net 2 ? , is 3.0 / WCF already stable?
In case of installing on the dev pc , can I continue to compile and deploy my old solution to other pc's that have net2 , or I need also there to install net 3 ? (I mean that in the old solution I don;t add nothing from net 3 wcf etc... I will use the wcf in other project )

5. where I can find simple tuturial some p2p "hello world" in wcf (c#) ?
without diving into the bit's...

thanks

Hi, check my answer on networks NG and use cross-posting ( few groups together ) and not multiposting next time, so all the answers will be seen in any group . In addition look at http://msdn2.microsoft.com/en-us/library/ms733761.aspx

hi ,

I can answer to your 4th point :

..Net 3.0 comprises of .Net 2.0 and the additional components like WCF, WPF, etc..

So when we install .Net 3.0 in a fresh machine the install installs .Net 2.0 + The additional components.

So when you r in a old machine, when u install .Net 3.0, the install checks if there is 2.0 already present , if so the install just installs the new components only .
Vs2005 does not have any impact when u hvae 2.0 and when trying to install 3.0.
Thanks
