Service Host application and client apps on remote machines

Hi guys,
i want to create a solution for my graduate work but i need some start hints.

My major point is how to create a service runing on an application which shares mrthods for other apps. Users can view the server values through read only methods, ang change "x","y" values through single-call methods.

All objects are created on a serv machine, usrs has only limited access to it's values.

I already know how to set a service and change values on usr apps.

As i immagine it would look like:
(of course there can be more usrs)

________      ________
|      |      |      |
| usr1 |      | usr2 |
|______|      |______|
    \           /
     \         /
      _________
      |       |
      | serv  |
      |_______|

1. I'd like to use WCF and Windows Forms.
2. Each of usr or serv works on a remote machine.


Serv:
* For example a few int values, each one in an other ticker (for example interval=100ms)
*

int value1=0;
int value2=0;
ticker1
{
value1+=x;
}

ticker2
{
value2+=y;
}

*Serv app contains "start" and "stop" buttons for start or stop the hosting services.
*Serc app can do everything that usrs can (changing values, etc)

usrs:
*User app has a view on a value1,2 ... n (for example labels).
*Each user has a ticker that refreshes the values (i don't know if thats a good way to create a 5 secound ticker to refresh values? if there is a way to refresh it instantly?)
*Users has a possibility to change the value of "x" or "y". for example text box.


ps. i know some of WCF bindings, contracts etc.. i already have whole coulorful idea i just need a good start point to not start everything all over later.


guys:
Maybe You could share with me Yours points of view for my solution. If my post is not clear or understandable please notify me of it. I'll try to explain it as good as i can.

Cheers
