Help in a ADO.NET Project

Hello,im doing my project of end course in computer engineering. My problem is this. I have a application server , that uses ADO.net to get tables and such from a SQL Server DB ,and i put the tables on a DATASET , and im planning to send via TCP that object to a PDA , that is running a application developded in Compact framework.net. (im currently building the server application , so this idea of using a dataset in still fresh) The PDA Aplication is for business , it has client tables and so on, all like a vendor. My question is this, is the best way of doing this using a dataset? (i dont want to use webservices unless its the only way) Another question , is how to i serialize object in the compact framework.net application? I never developded serious applications so i don't have a clue on the best way to go .
