What kinda of C++ application is it, George? Gabriel Cuvillier, the dev that did the Doom 3 demo port, used lazy loading to instantiate the initial download and get the user into the menu which is a small 15MB download.
I've been thinking a lot about heavy 3D graphics applications on the web with late code sizes, and fetching the assets in small chunks as needed is definitely the best option for now. Will be interesting to see with WASI if you'll be able to use your local hardware storage natively to download these big files too, which would be a hybrid web/desktop approach. Having some sort of file manager window in the canvas for big WASM applications is a good idea too I think.
