The System::ConfigSync::upload_file() and download_file() methods will allow for generic uploading and downloading of files to the BIG-IP filesystem from the maching running your iControl client. We currently don't support having BIG-IP be the initiator of a file transfer to another system. Also, there is no programmatic way to execute programs on the filesystem. Imagine accidentally sending a "rm -rf /"... Granted certain areas are protected from the iControl process, but this would cause just enough damage to make things unworkable. We decided early on to not include this feature.
