Certificate Authorities like Verisign confirm that you are really who you 
say you are and their certificates are already preloaded on everyone's 
PC.  Redhat sticks all the commercial CA's into a file called 
/usr/share/ssl/certs/ca-bundle.crt.  Microsoft have a similar file 
somewhere.

You can accomplish the same thing by using a self signed certificate but
you have the problem of getting your self signed CA added to your client's
bundle.  When your clients first log into your server they will see a
popup saying that your certificate is unknown and will be asked if they
want to proceed.  They can add your cert to their bundle at this time.

This is quite workable if you have a limited number of known clients who
you can instruct ahead of time on what to expect/do.
