There is no way to move a SqlConnection to another machine, or another
process.

I suppose the work around depends on what you need to do. If the web
service needs to make a connection to a database it knows nothing
about, you could encrypt and send the connection string to the web
service (assuming the connection string would be valid for the
service's security context).
