&gt;The software is not developed yet.<p>I actually develop an online whiteboard, so if you are interested in licensing it let me know (send an email to the email address in my profile). You can easily run it on your own server, customize it, etc. It&#x27;s incredibly stable, and is used by a large number of online tutoring companies.<p>&gt;Would offering a stylus with the software be enough of a unique value proposition?<p>You really do need some kind of graphics tablet&#x2F;stylus if you want to do decent freehand drawing.  A lot of my customers use Wacom tablets, and they work very well. It&#x27;s certainly an interesting idea to bundle them together...that isn&#x27;t something that I&#x27;ve tried.
