Getting a bit ahead of myself here.
Assuming I start selling a product based on the spark core and then want to update the firmware on said products. Are there any available tools for deploying a single firmware to hundreds of cores simultaneously or is this non free secret sauce?
Hi @mrOmatic,
Good question! We’re working on a suite of features for product creators that include fleet management so you can manage and deploy firmware to your products. 
We’ll have more details in the coming weeks, or you can always email Dan at sales@spark.io and the sales team can help answer those questions in more detail.
Thanks!
David
