I don't think NCM could do the uploading unless you can change your config archive location to the appropriate directory on SharePoint. LEM might have more options based on file creation within a directory, but I think you would still need to run an external script to upload the files to SharePoint. And if you are going to have a script that does the uploading, you could have it check your config archive for new files as well. As far as what external programs SolarWinds can use, I believe it can run anything the server it is running on can (at least that has been my experience so far with the alert actions to 'run an external program'. And finally I don't know a thing about PHP. I hope that helped some.
