Thanks for the explanations if everything WASM related. I now understand much better what you have.

frame index seems weird in a memory read packet. Seems like the module ID should be passed instead of the frame index.

Reading memory could be handled with memory identifiers, or segments. Currently the packets for m and M only have an address, but someone out there must support reading from CODE and DATA address segments in the DSP world. I have an email out to Ted Woodward to see what they do for Qualcomm's hexagon DSPs. I'll let you know what I find. Maybe each WASM module can identify N segments it needs and each module would have its own unique segments. Are module ID's just 1 based indexes?
