This site is hosted on my MyWireless connection with Apache & PHP (WIN32). I also run my own nameserver (for the rational.co.za domain) (SANS from sf.net). A zoneedit.com NS may work better.
As for mail, I run my own mailserver, with no backup MX. I've tested this
setup with a mailing list, and I'm losing less than 0.1 % of mail, which is
pretty good considering that the connection is broken for various reasons
about once a day.
