Asheet,
Below is a small example applet that displays a multi-color text (red for first user, blue for second user). To try it, run the applet, enter some text, and click the corresponding Submit button.
NOTE: This is just a little example of how you might extend Canvas to achieve the effect you want. It is not intended as production or release code. Please modify to suit your needs.

import java.applet.*;
import java.awt.*;
import java.awt.event.*;
import java.util.Vector;
public class Test extends Applet implements ActionListener
{
    TextField redInput; // text input here will be displayed red
    TextField blueInput; // text input here will be displayed blue
    Button submitRed; // use to submit red text
    Button submitBlue; // use to submit blue text
    ColorCanvas history; // the area where the multi-colored text is displayed
    Vector text; // holds text and color selections entered so far
    public void init()
    {
        text = new Vector();
        setLayout(new BorderLayout());
        Panel top = new Panel(new GridLayout(3,2));
        top.add(new Label("Red:"));
        top.add(new Label("Blue:"));
        redInput = new TextField(20);
        top.add(redInput);
        blueInput = new TextField(20);
        top.add(blueInput);
        submitRed = new Button("Red submit");
        submitRed.addActionListener(this);
        top.add(submitRed);
        submitBlue = new Button("Blue submit");
        submitBlue.addActionListener(this);
        top.add(submitBlue);
        add(top, BorderLayout.NORTH);
        history = new ColorCanvas();
        ScrollPane sp = new ScrollPane(ScrollPane.SCROLLBARS_ALWAYS);
        sp.add(history);
        add(sp);
    }
    public void actionPerformed(ActionEvent ae)
    {
        if(ae.getSource() == submitRed)
        {
            if(redInput.getText().length() > 0)
            {
                text.addElement(new ColorString(Color.red, redInput.getText()));
                redInput.setText("");
                Graphics gr = history.getGraphics();
                history.update(gr);
            }
        }
        else if(ae.getSource() == submitBlue)
        {
            if(blueInput.getText().length() > 0)
            {
                text.addElement(new ColorString(Color.blue, blueInput.getText()));
                blueInput.setText("");
                Graphics gr = history.getGraphics();
                history.update(gr);
            }
        }
    }
    private class ColorCanvas extends Canvas
    {
        int width = 800;
        int height = 1000;
        public Dimension getPreferredSize()
        {
            return new Dimension(width, height);
        }
        public void paint(Graphics g)
        {
            int orX = 20;
            int orY = 20;
            for(int i = 0; i < text.size(); i++)
            {
                ColorString cs = (ColorString)text.elementAt(i);
                g.setColor(cs.color);
                g.drawString(cs.text, orX, orY + (i * 15));
            }
        }
    }
    private class ColorString
    {
        Color color;
        String text;
        ColorString(Color c, String s)
        {
            color = c;
            text = s;
        }
    }
}

Hope this helps.
