Questions on GNAT, open source and cloud computing

[reinert <reinkor@gmail.com>]

Not directly related to Ada (technically), but:

I still work on making my (Ada) experimental software (for microscopy) available open source: https://korsnesbiocomputing.no/

Before I put it on GitHub, has anyone ideas about headers in source files? 

And are there any possible issues related to making the software available as an online service via "Cloud Computing" (virtual servers via for example Apache guacamole: https://guacamole.apache.org/) ? This could make it easier than otherwise to collaborate with users/developers and to introduce new features and correction "on the fly" available for users.

It will cost somehow to operate a virtual server (the software needs computing resources, space for storing data etc - and one must pay for compiler?). Users could cover these costs. So is it possible somehow to protect such cloud computing small business combined with open source? Anyone can on daily base copy (almost mirror?) if they see money in such cloud computing for my program?
