File transfer between pda and desktop server.

hi, guys

We are going to use .net CF to develop a product on PDA, and we need to transfer some data between PDA and our sync server. On PDA, we are going to use SQL CE, and there is a SQL Server 2000 on our sync server. We need to exchange some data including the data in SQL CE and some data files, like images taken by users. We are trying to find our a good solution for that.
For the data in SQL CE, I think we can just use RDA. We don't have too many complicated data to transfer. And we need high speed. So, RDA should do.
For images files, we are thinking about, just use HTTP WebRequest to post the file to asp.net web server, and save it to web server. We want to use some standard methods to do all of these. Do you guys have any suggestions about that

Thanks a lot.
