[rabbitmq-discuss] push server for android

[ludy]

i want to do a push server for android. e.g i have a cluster of two
nodes,one named rabbit and another named hare. if too many clients
connected to rabbit connect the cluster,the socket descriptors of node
rabbit is full.
my questions are:
1.when node rabbit is full,how to redirect/connect to another node??
2.erlang can support 60000+ tcps,if need loadbalance,can loadbalance
support 60000+ tcps???  
3.are there some other ways to implement push server for android??
