Hi,
What kind of PDF's do you want to send to SharePoint? We developed an extension called 'NXTdim Vault' which adds quite some functionality to Vault. It comes with some job handlers as well. One is capable of creating PDF's (and many other export formats) of Inventor documents documents on a life cycle change and another one is capable of uploading these export formats to a SharePoint document library on a life cycle change.
The current upload mechanism is limited to export formats (PDF, DXF, DWF, IGES, etc) of Inventor documents, but we are working on a completly new Vault-SharePoint integration. If you want to get more information please send me an email and describe the workflow you're trying to achieve. (what kind of documents do you have in your Vault? What kind of documents need to be published and why? How is SharePoint being used? etc.)
More information about our extension can be found here: http://www.cadac.com/nxtdim/en/nxtdim-vault/Pages/nxtdim-vault-edm-pdm.aspx.
