At least doesn't sound as if he's involved full time anymore.

And more evidence he isn't at THTF anymore:
"Did you work for a China company? Yes... I was Vice President/Strategic Development for Tsinghua Tongfang for one-year, a US$20 billion market cap China tier-one consumer electronics manufacturer. During my time there I designed and brought to market five category defining new hit product lines, including the LimePC brand of PowerPC based miniaturized consumer personal computers at CES 2008." http://www.aboutjack.com/faq.shtml
"In mid-2007 I accepted a job as Vice President of Strategic Business Development for Tsinghua Tongfang Co., Ltd., a $20 billion market cap public company in China. Working from their Shenzhen R&D facilty I steered a group of exciting new products through the design, development, and go-to-market process, including an all-new line of miniature PowerPC-based personal computer products under the company's new LimePC brand name, shown at CES 2008 in Las Vegas to a terrific response from both media and the market. I left THTF to return to full-time consulting in Spring 2008." http://www.aboutjack.com/bio.html
