Would a cloud version be applicable for Glyphsapp with annual membership?
Just to avoid long waiting for Appstore in updating !!
The regular version from the website (and only a bit slower the App Store version, too) work kind of like a subscription. You pay once and get new features all the time (check out the change log (http://glyphsapp.com/updates/changelog.php)). So you get the best from both models: A lot of new features and an unlimited license.
