Props to the team, this is great work.

I've been trialing Preview 2 for the last couple of months to good results.

I do have one problem though and can't seem to find a good way forward. My use case is to use WASM for the data processing modules in a tile-based simulation game/engine. This involves passing around large (many MB) buffers. For any semblance of performance the data cannot be copied between modules and needs to be passed by reference.

To that end, I've implemented Resources. However, getting data out of a resource still requires copying (wasm-bindgen makes the return types from accessors owned Vec<>). I've resorted to just passing u32 memory offsets since all of the modules are sharing one Memory.

Would love some guidance on this as I've scoured the Internet and simply can't find the right solution, if there even is one.
