Offline Google Docs client coming?

One unlucky Google Docs user received an error message while using the service that some think could suggest an offline client is coming -- something that I definitely believe will happen sooner or later.  Instead of a standalone desktop client though, I lean towards the idea of a website or firefox addon that can be used regardless of your network status.

"We're sorry, but we were unable to upload this document.
If you have the desktop word processor installed on this computer, there are two other easy ways to bring the file into Google Docs & Spreadsheets"

Of course, this error message could have been a typo -- one comment in that thread from someone who identifies himself as "Anonymous Googler" says this is the case.

There are a couple reasons I think something like this is in the pipeline though.  First, there is code behind the scenes that references "localhost" -- network types will know this means "your machine". 

if (location.host.indexOf("localhost") > -1)
{
  if (location.host.indexOf("Prefactor") > -1)
    return "http://localhost:8180/Prefactor/" + page + paramString;
  else
    return "http://localhost:8180/Docster/" + page + paramString;
} else
  return "http://" + location.host + "/" + page + paramString;

function RunningOnLocalServer() { if (typeof onLocalServer == 'undefined') return false; return onLocalServer; }

The second reason I think some sort of offline capability is coming is simply because Google has been really pushing Google Apps to small to medium sized businesses recently.  However, these businesses live in the world of portable computers, and a client that requires the internet isn't optimal, or acceptable.
