Is this just a PSD mockup or are there functional UI's?
css, js etc?
Is there a way to release template to community to work on their own skins?
JahPowerBit has plans to convert it into a standalone app. Until then you will have full access to the code (its basically just a webpage) so you can tinker around with things. All though I don't recommend this for most users if you are just changing background images then by all means.
That image was a PSD mockup which is a modification of the original theme mockup I did. I mentioned that some elements had or will have been changed before the final product because of font-changes, code problems, etc.
This is how I work. It would be more work to actually code the new theme into the site just to see if the donator likes it.
This is the functional GUI (coded) complete with color selectors for the elements:

If JahPowerBit agrees we can release it to a few forum members to test out. You will need to request a build from him though.
I understand you may not trust me (I commend you for that) but there were some things out of my control.
JahPowerBit is optimizing the system:
JahPowerBit: When you finished the V1 of your design, i will rewrite all the javascript/css, to have only one requirement: jquery. It's a lot of work, but it's worth, and it will be more secure.
Also my continued addition of elements and new themes is stretching our time frame

I send JahPowerBit a build almost every night of my progress before I go to sleep.
He has already payed me for my work from the bounty funds.
You can be sure he didn't pay me until he saw work from me.
The developers trust him, and he trusts me.
Have I satisfied your trust now?
