I don't have anything contemplated--just suggesting a general idea.

Regarding how much disk space it takes up, would depend on, as when one installs the regular BIAB, how many of the RT and RD packages they wish to install.

And no, that is not uncommon. How many gigabytes do you think orchestral sample libraries take up? They also come in plugins--of the three types mentioned, and require installation of the huge sample libraries.

Of course there would have to be a major difference in pricing, depending on what the person already has. If a person already has the BIAB ultra-pak, with all the RD and RT paks, and just is adding the plugin itself, I would expect the price for just the plugin should be fairly inexpensive, or be included itself in the Ultra-pak.

Whereas, if someone is starting from scratch with the plugin, they would be buying much more than the plugin itself, but also RD and RT packages, etc., depending on what they want.
