I've just begun to read the QB Developer documentation and have come to the conclusion that to write a web-enabled application that will sync/remote backup QB files between two machines over the Internet, that the QBWC is the 'approved' way to accomplish this task. The .NET application samples in the QB SDK (V12) are not using WCF but WSDL and SOAP.
But before I commit to going that route, I am asking if anyone has a better approach. I'd prefer to use WCF and MS Sync Framework, but I don't want to head down that road if it will mean using a cannon to kill a mosquito.
Thanks
