I have no idea what SF Mac ISV is. I wouldn’t know one if I tripped over one. However, independent developers may want to check out their planned WWDC get-together for Sunday, the 10th of June. The soirée runs from 5:30 to 8:30 PM with food and drink, allowing small companies and independent developers to network. The sfMacISV webpage is sparse on details but it looks like the event will be free for the first 50 developers to register and $20 thereafter. For more info, contact Chuck Soper via this RSVP page. And if anyone has any further information about who these people are, please feel free to drop a note into the comments.
