Cool!
BTW any reason why you parse the HTML and not use the JSON index?
Also adding a new API route to the dub registry might be a bit 
API friendlier then fetching all packages on every cron 
operation. Generating the index JSON is rather expensive (until a 
few recent fixes, you could kill the registry by requesting the 
index.json a few times in a row). Though of course the dub 
registry (or its reverse proxy) could cache the result for a 
bit...
