Do you have a specific hardware target in mind or is this a proof of concept on a single hardware setup? Also, any specific issues you've had in converting this over to WebGL or is WebGL just not something you frequently work with? I just want to make sure this is possible, because looking over the merge sort code on the link, it looks like it should be, so I'm wondering if I'm overlooking something. Send me a private message and we can talk over some more details, thanks.
