RemoteObjects is an objects server for Smalltalk. RemoteObjects is a Smalltalk framework wich allows you to use objects from other Smalltalk images over the network. It has focus in efficiency by reducing overhead as much as possible. Several serializers can be used so interdialect interoperation will be possible. Different policies for attending incoming sockets and message dispatchal can be used so this should allow to make a very customized objects server. Take a look into: http://remoteobjects.pbwiki.com
