Hi Roger,
I've been straggling to packed all required bins and installation file for making a NPAPI for nw, and i thought you might already done so before, if you can in future versions of node-webkit, you can create for us a common npapi wrapper that we will just bind function names or scripts and put a .dll file and link to it like node-ffi or something.. this can be however greatly add to a security to some business logics and extend nw a lot more. I hope i am making sense :)
I like your work-- web dev arrousal dream come true i must say, would love to drop you a cash or your group someday.
