In the past few weeks we've seen the introduction of a couple of CiviCRM Application Service Providers (ASP's). This is indeed good news for the CiviCRM community and gives the smaller organization a more cost effective and simpler solution to manage and host their web site and data.
The first one out of the blocks was CivicSpace On Demand. CSOD offers Drupal 4.7, CiviCRM 1.5 along with a few other useful drupal modules including CCK and Views. The CiviCRM install comes with CiviMail, CiviContribute and CiviMember.
Peter Hirst a long time CiviCRM and CiviMail user and contributor announced OpenSocialSites.com a few weeks ago. OpenSocialSites.com is based on Drupal 5.1, CiviCRM 1.6 and can additional drupal modules can be installed per your needs. It also comes with the other CiviCRM components including CiviMail, CiviContribute and CiviMember. Peter is also offering Joomla + CiviCRM hosting which will serve our ever growing Joomla community needs quite nicely
