Hi Max, I'm not sure about that, there could be some complications like trying to send binary data back and forth using strings can run into problems with things like illegal character encoding sequences and 0 values being treated as end of string markers.

There is a new kind of "typed array" thing that's meant for working with binary data in JavaScript but the version of JavaScriptCore that MoI v4 is currently using doesn't seem to have it included in the JSC API yet. That might not be possible without updating to the latest QtWebKit which is unfortunately a highly time consuming job.
