Didn't he say DSL? My DSL changes IP addresses.
I was thinking about getting something like

to remotely support them using a reverse connection VNC
Does anyone else use that?
Yup - I use dynamic DNS. I use ddclient to maintain my IP - it has
about a half-dozen different modes of operation and supports numerous
dynamic DNS services. Ideally you point it at your router and it
notices if you IP changes, but worst-case it can ping a server outside
to find out what IP you're coming from.
Note that various dynamic DNS providers have varying TTL policies.
Often if you pay more you can get a shorter TTL. If you IP changes a
lot a shorter TTL will mean less effective downtime.
If you're receiving mail on a dynamic address you should consider backup
MX service. Also, consider that anybody else you gets your old IP could
potentially intercept your mail if they aren't nice. However, if you
aren't encrypting your email and using only mail servers that
authenticate connections you should assume that email is both unreliable
and always read before you get it anyway. (Grr, why hasn't somebody
fixed email yet?)
