confused with realvnc, tightvnc, xf4vnc, etc

[Tony]

I am a great fan of VNC largely because it lets me access my Linux X 
sessions over the Internet from a Windows machine anywhere.  I would 
also like to be able start offering a Linux "terminal services" type of 
solution to my customers instead of th MS one.

I started with the AT&T VNC (now RealVNC) and then discovered Alan 
Hourihane's excellent xf4vnc project and started using his Xvnc program 
as a drop-in replacement.  The thing that took me to xf4vnc was the 
support for TrueType fonts that comes with the XFree86 version 4; this 
immediately solved all the font problems that I had been having.

Then I discovered TightVNC, which claims a number of benefits but seems 
to have the same fonts problems as RealVNC.  

Here's the question that I still have after quite some looking around:

If I must have TrueType fonts and bandwidth optimisation is also very 
important, how can I find out what each of these alternatives has to 
offer?  

Regards,
