Not too soon. We will try to get this into the next major Axis2 release,
which might not bee too soon. We are still doing some R&D in this area. I'll
be posting the findings and related stuff on my blog,

work on EC2 at the moment. This is because the Group Membership Protocol (GMP) uses \
multicast based member discovery. However, when you start two nodes on EC2, \
generally, the IP is randomly assigned by Amazon from a list of available IPs, unless \
you use elastic IPs. Even if elastic IPs are used, you cannot request for a specific \
IP address, hence it is difficult to get the two IPs such that they belong to the \
same multicast domain. Anyway, Amazon disallows multicasting at the moment.<br>
<br>We are investigating whether we can use some other mechanism for group membership \
management.<br><br>HTH<br>Azeez<div><div></div><div><br><br><div \

this AMI, and on this AMIs I started an Axis2 instance each. However, I found that \
these Axis2 nodes cannot communicate with each other. I have enabled the cluster \
