I have a server on a permanent modem connection with a fixed IP address. If
you don't have that then you try and find it. There are companies that offer
suitable access to a server to allow this sort of thing for a small fee.
Also ISPs offer a variety of Co-location type services. I have included the
URL for a site that charges $100 startup fee and $200 per month for 20G of
transfers, for that you get your own Linux server that you manage yourself.
The site is in .NL, it's got good connectivity to Europe and XS4All has good
a good record regarding privacy and protection of customer's rights (they
won't close your site if a cult threatens you).

I have been considering this for some time, but at the moment I don't feel
that it justifies $US200 per month for the amount of use (maybe at some
future time).
I will set it up if one of two things happens:
1) I find a few people to share the costs with and we can all suitably trust
each other (trust the skills and the intentions) such that everyone can have
root access - or have some people who just want user-level access.
2) I find a lot of spare time or find some people to help me so that I can
develop some of my online-community ideas. In this case I'll have a need for
several gigs per month of traffic and it'll be worth the money for me to pay
$US2400 per year.

Here's my rlinetd.conf settings:
service "ssmtp" {
port "ssmtp";
user "foo";
exec "/usr/bin/ssh foo@server -p 22 -C /usr/local/bin/localsmtp";
nice 5;
interface 127.0.0.1;
tcpd;
}
localsmtp is a script that runs "/usr/local/sbin/pass 25 127.0.0.1" because
ssh doesn't seem to like giving command-line parameters when run from inetd.
The program pass makes a connection to port 25 of 127.0.0.1 and passes data
between stdin/stdout and that port.
Note that local account foo has a ssh RSA key that lets it login to account
foo on "server" without a password.
I think that there may be a better program than pass in Debian now, maybe
netcat will do it.
If not let me know and I'll package pass. I probably should package it
anyway, the later versions of pass have some nice features such as the
ability to connect to one of two addresses depending on where it was run from
(a feature which allowed me to make a crappy Lotus Notes mail server work
without redesigning the network around it).
