I recommend you contact your sales representative (or the MathWorks Sales department if you have not already purchased the product) and describe your desired workflow and constraints to them. They can describe various licensing and setup options and explain how they may support your workflow.
Since you mentioned bandwidth is a potential issue MATLAB Online probably isn't an option, but perhaps locally installed MATLAB sessions running your code on a cluster using Parallel Computing Toolbox and MATLAB Distributed Computing Server may do what you want.
You can contact Sales using the Contact Us link in the upper-right corner of this page.
