Summary:
The QE5 editor binary and source, the in-house development tools, and any other tools, sources or art collections should be released on a CD, shipping with the game, or as a separate kit product.
Advantage:
Competes with other companies releasing game tools along with the game. Emphasizes the extension/open character of the product. Makes it easier to enforce a EULA that does not allow CD ROM distribution, while keeping in mind those majority of customers that do not have cheap Internet access.
Disadvantage:
Takes additional space on the CD ROM, which might not be available. A second CD might add to the costs of the product. A separate product might be too expensive, distribution-wise.
Putting it along with a sold product raises issues of support and maintenance.
Effort:
In-house tools have to be wrapped up for distribution.
Alternative:
Unsupported release by Internet.

Running the game ref_lib >for the editing 3D preview? I hadn't really considered it, but we might. Trinity is still likely to require extensive preprocessing, but loading the ref_lib could still be a usefull workflow enhancer over running the entire game. I'll have to consider that.
