How to serialize an entire data store

[dlapointeus]

I'm sure I'm missing something basic here. We have a store which uses a LocalStorageProxy. Is there a method to serialize an entire store into a format (json) that we can post to a web service? We want to give the users the ability to click a button and have all the local data synchronized with what's on our server. I can see how to do this with each record, but was hoping the entire store could be serialized at once.

Thanks in advance for any help.
