Connecting to S3 bucket with Python and Personal Gateway

Hi,

I am developing an enterprise level data model and need to connect to an S3 bucket to pull the data. The ideal way to connect would be with a Python script, we have tested and works well in desktop.

I have read that the only way to refresh in Service is to use a Personal Gateway. Since it is a personal gateway and can't be shared with other developers, my first thought is to connect as fallows:

S3 Bucket -> connect to Dataflow via Personal Gateway -> give other developers access to Dataflow.

Are any foreseeable issues with this setup? 

The end goal is to embed for customer and automate the dataflow creation, one Dataflow per customer. I have my hesitations that this will work and am not sure it is scaleable.

Any guidance is greatly appreciated.
