Just made a post in my personal blog that is probably of interest to mojoPortal fans.
It has a screen shot of the SiteOffice UI showing a little google gears client database admin tool I threw together.
UPDATE 2007-06-24:
I've updated this site with the latest code, so anyone logged in can try the google gears query tool. After you login, click the Site Office link at the top then go to My Stuff > SQL
You can create tables, insert, update delete, select etc. Pretty cool huh?
