About your PowerPoint question.. I don't know how to put this, but I think just the fact that you ask, means that my message did not come across clearly. Or do you know the answer and just want to say that I need to make this more obvious? :)
To answer the questions:
It is not better than a PowerPoint PDF export, but tries to solve the problem of doing many PowerPoint PDF exports while changing the content of the document on each export. This is doable by just sending a template document and some keys and values to be replaced.
The main pain it solved for me was that I don't need to do layout changes for my customers if they are using some of my software and want to change the layout of lets say a report or proforma.
Does this make sense?
About the targeting to sys-admin types. This is correct. Perhaps I should split the page into 'marketing' and 'read if you can code'. I will think about that.
Thanks!
