[Spread-users] Trouble compiling spread version 3.17.1 in VS.NET 2003

The reason I am interested in obtaining the IP addresses is that I am
attempting to implement my own messaging protocol (namely, pbcast aka
Bimodal Multicast). I would like to use Spread to tell me who to send
the messages to, but how I send the messages will be determined by my
protocol. Therefore, having the name of the user isnt helpful unless (as
I said before) the name of the user IS their IP address.
Here is specifically what I am trying to do. The pbcast protocol
requires me (at some point in the protocol) to unreliably send a given
message m to every group member with probability p, where p is the
probability a member is chosen to receive the message. Another part of
the protocol requires me to randomly choose one member of the group to
gossip with. Do you know of anyway to do exactly these things?

So, you may need to do something interesting where you have a naming scheme for subsets, and represent each with a group such that each member joins the groups representing each possible subset it is in.
