I have done a whiteboard software in JAVA APPLET/SERVLET application
so that 2 or more persons can communicate with it through a website.We
have done a trial with it which revealed a problem-distortion of
letters while
writing on it with a usual speed, especially when it is shared by 2
ore more users .My programmer said that there is no way to correct
this .So I am in search of the exact technology with which it can done
correctly.  I want to know the most appropriate language with it can
be done correctly. Please note that we have to do voice chat software
also.

Clarification of Question by rsratheesh-ga on 01 Aug 2006 08:19 PDT

This was the message my programmer send about distortion  
?The root problem is that Java is only recording mouseDragged events
at certain time intervals rather than pixel to pixel, so if you write
fast, then you're correct in that it gets a bit choppy. I imagine that
Sun (the makers of Java) likely did this to avoid having too many
events to process, but whatever the reason the code that controls this
is only something that Sun themselves can change.
As you can see here others have close to the same problem in Java:

I want to know
1.Will there be such a problem or any other difficulty like this if
software is done in PHP/.NET or CGI?
2.Which of these are platform dependent?
3.Which of these will work in tandem with a voice chat software in
made in the same language?
4.Other problems if any.

what is distoring the letters? the physical whiteboard? the input device?
you need to narrow down the problem to hone the solution
