So? There are many instances of (open-source) Giac already deployed on Google servers, and perhaps servers of other commercial cloud computing providers.

While in principle it would have been good to have Giac on board, OpenDreamKit is a consortium of like-minded people, otherwise it'd have been a constant fight and no work done. Giac project appears to ignore cloud computing possibilities and the universally adopted across OpenDreamKit practice of using source version control to facilitate collaboration on the code. I cannot comment on why certain implementations did not use Giac code, I am not involved in this work. > If I have an opportunity to test on a University server I'll take it, but I > will not fight for that. If I don't have the opportunity, then I'll try on the next laptop I will buy when the current one will have to be replaced.
