This week I finished migrating the last of my clients' applications over to Heroku from SliceHost. This has dropped the hosting fees for most of them down to zero while at the same time really impressing my clients with significant speed increases. I might have been able to get the same performance increase out of SliceHost if I was more skilled at sysadmin but I'm not a sysadmin.
If they are fairly low traffic sites with small databases (< 5 MB) that don't require SSL or more than a daily cron, they should fit within the parameters of a free plan - i.e. "blossom" database server, 1 dyno, etc.
In the process of migrating a large app to the cloud via Heroku. (We have other apps already running there.)
The guys there are awesome and very helpful, and the service is mind-blowingly bad-ass! Amazing how Rails deployment has evolved!!
SNI (http://en.wikipedia.org/wiki/Server_Name_Indication) attempts to fix this problem with SSL, but XP (and Chrome) don't support it yet.
