This should be simple to lot of Remoting guru's out there 
1. How to pass business objects to remote method calls

3. Does the object needs to implment ISerializable interface or have an <Serializable> attribute
4. Does the object needs to inherit MarshalByRefObject
5. How to generate a proxy remote hosted on an IIS with binary formatting
6. Any pointers to web articles is greately appreciated !!
Objects passed as parameters to a remote method call
Mike Cating
It all depends on what you want to do. If all you're trying to do is pass data to a remote call, it needs to either implement ISerializable or have the attribute. If you'd like to maintain a reference to the actual object on another machine, then you need to inherit from MarshalByRefObject.
There's a good architectural overview of remoting here:

Alongside that article, there are about a dozen articles discussing different aspects of remoting. May's MSDN Magazine has an article on designing a distributed processing system using remoting here: http://msdn.microsoft.com/msdnmag/issues/05/05/DistributedNETRemoting/default.aspx
