Archiving tracking info for import into a Piwik server that is offline (no replies)

I am not able to setup a Piwik server that users can access in production due to system requirements (Microsoft stack).

I would like to setup the client-side JavaScript and a reimplementation of the server-side endpoint to collect all the information which I would later feed into a Piwik server running in my dev environment.

Any pointers to anyone already doing this, any existing formats/mechanisms for bulk import/export of Piwik events, and/or what I would need to do for the endpoint reimplementation?
