HTML5's localStorage databases are usually size-limited — standard sizes are 5 or 10 MB per domain. Can these limits be circumvented by subdomains (e.g. example.com, hack1.example.com and hack2.example.com all have their own 5 MB databases)? And is there anything in the standard that specifies whether parent domains can access their children's databases? I can't find anything, and I can see arguments for doing it either way, but it seems like there has to be some standard model.

From http://dev.w3.org/html5/webstorage/#disk-space
A mostly arbitrary limit of five megabytes per origin is recommended. Implementation feedback is welcome and will be used to update this suggestion in the future.
It also mentions that a user agent should guard against circumventing the main domain storage limit, but is short on details.

I missed this question when I asked "Is 5MB the de facto limit for W3C Web Storage?", but I got basically the same answer. If you want more information, I did link to some browser specific limits in my question.
