Try HomeCamera
I understand where Logitech's coming from - they're targeting folks who're NOT tech experts and who can't be bothered with setups, cabling, Linux, etc. These are people who have money, trust the Logitech brand, are comfortable with non-tech DIY... a large large market, IMO.
While I'm at it, another service targeting similar folks (though its free and webcam based) is HomeCamera (http://www.homecamera.com). No video streaming (only video clips), though that's set to change early 2009. Motion detection alerts (including videos) are sent direct to mobile phones, storage is all server based, sharing is easy, scheduling of recording is easy, yada yada yada. Covered by Technofile on Sky News a few months ago (the video should still be there somewhere...)
