Google Chrome OS is back in buzz again. And we’ve something critical to talk about. Although, there hasn’t been any official word about Chrome OS for quite sometime now, the web diggers (aka geeks, bloggers) were right on their job, trying to dig out any possible traces of Chrome OS and they’ve somehow found one out.

The clue belongs to Chromium web repository, the Open source project that serves as a backbone for Google Chrome browser development. DownloadSquad spotted out a mention of Chrome OS login manager, somewhere buried in the open source code of Chromium web repository.

As Chrome OS is supposed to be a Browser based OS, a general interpretation of the term Chrome OS login manager would mean an OS that operates on Single Sign-On (SSO) cookie, working for all Google services.

In simpler words, you will be required to login with your Google Account when you will boot up your Chrome OS machine. Once you login with your Google account credentials into Chrome OS, you will get access to all the Google web services(Gmail, Google Docs, Picasa, Reader, Blogger, Friends Connect……)

It sounds pretty cool and absolutely perfect for a company like Google, probably the only internet company in tech industry that has in-house web based alternative to all major desktop applications and software needs. It also means that you just need to login with your Google account to any machine(home, office, friend’s) and you have your custom OS ready to be served. As all the services belong to Google, the overall compatibility will be immensely smooth.

But this presumption (which is most likely to turn true) that one must have a Google account to make an access to Chrome OS and use Google Chrome as the primary web browser for using any web service on Chrome OS has raised a lot of questions over the freedom of choice.

If somebody is not interested to work on Google Chrome(the supposed backbone of Chrome OS) but Firefox or IE or whatever else then ? Or if somebody doesn’t want to use Google Docs or Picasa but instead, want to use some other alternative software from a third party developer, then ??

Will Google allow other competitive software or services to get replaced as primary service in Chrome OS ? It’s a question that’s still to be answered by Google but we’re guessing that Google will choose to stay competitive than playing resistive.

Even when any user downloads and installs Google Chrome on Windows OS, Chrome first asks the user to choose a default search engine (in-built into URL address bar) and doesn’t just impose Google search on new Chrome user. It’s a competitive ideology that Google has always followed (so far) and we expect that for Chrome OS as well.
