Thanks for this comprehensive list which I hope will help people in search of such offerings. I've been told panix.com does also provides such service. I wrote that article because in specific locations that are out of the US and Europe, the offering might be even narrower. This was not made out of despair finding a nice provider, but because I found the technical challenge interesting (enough to share).
