Are there really that many companies - companies without their own IT department - with self hosted, unmanaged servers running around these days? Seriously?
Umm... yes - if you strike "unmanaged" -i t's pretty hard to find any computer that's completely "unmanaged" - somebody always does software updates, reboots when it crashes, and (hopefully) does the occasional backup.
If you're any kind of engineering company, it doesn't take an IT department to care and feed for a half-rack of Dell servers running Windows Server & Outlook, Linux + Apache + Postfix, or maybe a Mac running OS X server.
And an awful lot of home-based businesses have a server under a desk, hooked to a commercial-level broadband connection.
