OK, that's a no, and a no.. and also a no for the downlaods page on Snowcovered.
I jumped through all the DNNUpdate hoops and did find an update for a module by another developer, but funnily enough, one that I've never had installed. I'm betting DNNUpdate only looks at the module friendly name, because it's a fairly common one.
In any case, I'll get in touch on the Snowcovered helpdesk.
