Hi Johannes Took a quick look at comments of some DGV packages and it looks like they have put a lot of groundwork in. !Tric-P2P Chat commentStamp: '<historical>' prior: 0! This package represents a simple chat application that runs on top of AardWorks-Gossip. The idea is that the user makes him/herself available for chat. This effectively means that the node will respond to searches for the user's author initials. After searching for a user's author initials, you can open a chat with the user, sending and receiving data is done through the local AWGPeer. This app is a proof-of-concept. It uses floodsearching (e.g. broadcasting) and direct routing of packets, dynamically allocated and previously hardwired endpoints, etcetrera. In fact, this might well exercise most of the code in AardWorks-Gossip ;)! Maybe Croquet has some useful ideas for you too. Good luck...

Some weeks ago Stef was asking a P2P question and 'http://www.squeaksource.com/DGV' turned out to have a solution. But I didn't have the time up to now to check that is detail, still hoping that this point might be solved by a more up-to-date approach. It seems that I have to study DGV ...

I'm planning to use Zinc
and have a question, which might sound trivial for networking experts:
is it sufficient for Zn-Server to work if someone using Zn-Client knows my actual IP-adr (plus username and pw)?
Yes, that is enough: when an HTTP client knows an HTTP server (and the network is there) they can talk to each other, that includes ZnClient and ZnServer.
The challenge with P2P is exactly that: how will parties discover each other and will they actually be able to talk to each other at the network level (firewalls, ISP restrictions, etc..).
As always, http://en.wikipedia.org/wiki/Peer-to-peer is a good place to start.
HTH,
