Cool...
BTW - I don't think you'd need to cook in the Marketplace itself, but rather the Marketplace bootsrapper - which then downloads the latest Marketplace CAB. That's what I do anyway, and I get the Bootstrapper from here:
http://mp.windowsphone.com
Which then takes you to:
http://mobile.microsoft.com/windowsm...e.mspx?l=en-us
When you install it, that gives you the "Marketplace" icon in Start menu which downloads the newest Marketplace CAB.
BTW - I also tried Manilla by now. Again, it works great! I had some issues with Manilla in Miller's v13 (did not try v15) but it could have been a Winmo build issue too...
