Hello Lucius,

You are correct. Marshal is necessary in .net remoting world.
However, the DataSet and DataTable objects has inherited from
MarshalByValueComponent, and support the ISerializable interface for .NET
Framework remoting. These are the only ADO.NET objects that you can use for
NET Framework remoting. Please check the NOTE part in following document.
http://msdn2.microsoft.com/en-us/library/system.data.datatable.aspx
[DataTable Class]

Therefore, it is not necessary for you to implement all of the Remoting
Interfaces again in new DataTable-Inheriting class. Just declare it as
Serializable. Such as:

[Serializable]
class MyTable:DataTable
{...}

Hope this helps.
Sincerley,
