Mosync is oriented for C/C++ programers, you can make C2 work with mosync but isn't straight forward.
You can drop your C2 html5 build inside Project->LocalFiles but must keep the link with js/wormhole.js otherwise it wont work cause it needs the bridge.
For make a release you need to set your device targets link your profiles (developer licences/profiles/keys etc), and you must have the toolset (sdk, ndk, etc) for each target device in order to make builds.
You cant make a C2 html5 run with opengl just writing opengl=on, mosync give you a bridge, not a "port".
So if those things are complex to you, keep the distribution options that C2 bring to you.
Besides Mosyc Reload and Mosync SDK are 2 different things.
