Today Microsoft release the first pass of it’s Software as a Service (SaaS) offering with SharePoint and Exchange.  The prices seem fairly reasonable starting as low as $7.50/user for SharePoint.  I signed up for my 30-day free trial today, so I will post more as I get the chance to play with it and experiment with it.  If it is good enough, and has the features necessary, maybe I’ll even move my blog over there, we’ll see.  You can check it all out for yourself here: http://www.microsoft.com/online/default.mspx
