Transfer a Dataset Server to Server DCOM vs .NET Remoting?

I will develop a application, and the application will physically deploy as
three tier application: Web server, Application Server (Which host business
object) and Database Server. And We decided that we should host the business
object in the COM+ service.
Now I have a question that which protocal should I use:
DCOM or .NET Remoting. The special problem is:
How will DCOM transfer a DataSet from application server to web server, by
value or by reference? if by value it will be ok, but if by reference, may
be we need more consideration.

Can any one help me, thanks a lot.

The protocol (DCOM or .NET remoting) has no influence on how
objects will be marshaled. In both cases the DataSet
will be marshaled by value, because it's not a MarshalbyRefObject.

Deriving from MarshalbyRefObject would only affect Remoting. DCOM would not
care. Check out this article too:
