Hi Randall,
I use S-Drive streams for an embedded blog at
http://blog.fixtronix.ie and I have the data on my local machine thanks to Power Post (
http://www.coffeecup.com/power-post/ ). So if you want to be in total control of your data, but also have extreme flexibility, running your blog using S-Drive is the best option on the Internet, in my opinion.
You can update your blog from anywhere:

CoffeeCup, unlike many before them and many yet to come, are honourable, friendly, supportive & they give you userID and password protected access to your own data. Coffeecup have been in business since 1996 and they're not going anywhere anytime soon. So, before you entrust your data to your ISP or another blog host (who will control and limit your flexibility more than CC ever will), consider the facts. I speak as a CC software user from 1997-2012.
Your blog data is and always will be your data and when you use Power Post, you can never (ever) lose your data.
