OnLive's announcement on Wednesday that their streaming online service will cost $14.95 a month when it launches (not including rental or full payment for the games) took a few folks by surprise. However the folks behind one of its main rivals Gaikai told our sister site Joystiq at GDC today that there will be no such monthly fees to use their own service.

As we reported earlier today, InstantAction.com is partnering with Gaikai to use their tech to offer streaming PC games that can be embedded to any web site. Gaikai's founders also said they will have streaming servers at a whopping 300 locations in the US. In addition they say they have got deals with local broadband providers to put in servers at another 900 locations nationally. But when will all this actually go live? Unlike OnLive, who said their service will launch on June 17, there's no word yet on Gaikai's launch date.
