OK - here you have the first alpha version of Virtual keyboard plugin for HTMLArea.

I will test later a filter that could output just a button for launching external "layer" (iframe) with Google Virtual keyboard anywhere in moodle without editor - and with editable settings in administration menu. It could be done also with theme but let's try this plugin first. It will add a new button to editor toolbar for virtual keyboard.

To test it download a package from http://korpelainen.net/virtualkeyboard.zip and either unzip all those files (latest htmlarea and one lang file) to correct folders (lang and lib) inside your moodle or modify only the next 2 files and add 3 new files... 

File lib/editor/htmlarea/htmlarea.php:

line 177:

"insertvirtuals", "insertsmile", "insertchar", "search_replace",

line 280:

insertvirtuals: ["Insert virtuals", "virtual.gif", false, function(e) {e.execCommand("insertvirtuals");} ],

lines 1787 to 1804:

HTMLArea.prototype._insertvirtuals = function() {
    // Make sure that editor has focus
    this.focusEditor();
    var sel = this._getSelection();
    var range = this._createRange(sel);
    var editor = this;  // for nested functions
    this._popupDialog("dlg_ins_virtuals.php?id=<?php echo $id; ?>", function(imgString) {
        if(!imgString) {
            return false;
        }
        if (HTMLArea.is_ie) {
            range.pasteHTML(imgString);
        } else {
            editor.insertHTML(imgString);
        }
        return true;
    }, null);
};

line 2115:

case "insertvirtuals": this._insertvirtuals(); break;

File lib/editor/htmlarea/dialog.js:

line 35:

case "dlg_ins_virtuals": x = 420; y = 500; break;

New files:
lang/en_utf8/virtual.php
lib/editor/htmlarea/images/virtual.gif
lib/editor/htmlarea/popups/dlg_ins_virtuals.php

Beta version will come after some feedback and improvements...
