c# software updater - uses webservices

I need the assistance of an experienced c# web service developer. Using .NET framework 1.1 and sql.

I need a framework that will manage the checking of new software versions and update them either (1) automatically (2) by first presenting the user with a question. I.e. A new version has been detected do you wish to install etc. I like the system used by Itunes.. something similar to this would be great.

I'm thinking of using web service as the means of checking for the new software version and then a web service to download the file using binary transfer. I have a web site and sql db that can host the source binary files and version information. But i am open to suggestions. Should have file checking system, ie crc etc. Should be multithreaded. Should have a UI to upload files to client.

Must handle:

IMPORTANT! updating as a group of files, and wind back if one file in group fails files in sub directories

the files should be held as binary in my db on the web server

different versions of software ie download all version 1.2

all file types.. exe/dll/txt

the downloads should be compressed using Xceed compression

the client should be able to go thru a proxy server

one exe must be marked as the one that needs restarting

termination of running application to be updated

crc errors

file in use errors

other errors related to such a system..
