Looking for shared, extendable Whiteboard plugin in browser

ruby-talk
1

Hi all,

I am building a network application which will enable peer to peer
communication.The application is build using ruby on rails.

I am attempting to build a white board which will allow simultaneous
and syncronous developing and editing of Images.

I tried adobe SVG pluggin and other network image generation tools.I
need to integrate these tools with my ruby applications. my problems
are

1. How do I display applications written in c++/java script in the
browser
2. Adobe SVG pluggin is a exe. How do I render it in the browser and
syncronize the building of images on the network
3. Are there some other applications or pluggins which I can integrate
with ruby on rails and
   implement this shared white board in my application

Thanks
Sapna

With Great Difficulty (tm). As far as I know, the only way of deploying native
code over the web is ActiveX, and I don't know if you want to go there.

As for applications in JavaScript, DHTML (give or take AJAX, depends on what
you really need) is your best bet for this. Expect bugs, and know the content
of quirksmode.org by heart if you plan on supporting IE6 properly for the
more advanced (read: flashy) things.

2. Adobe SVG pluggin is a exe. How do I render it in the browser and

As for the SVG plugin, I think it's something all the users of your
application will have to install in their browsers. I admit I'm slightly
guessing here, because I don't have much actual experience with SVG on either
side, consumer or author. As for over-the-net drawing, I think you're once
again looking at AJAX, unless you know you can neglect the browser reloads
and the gruesome amounts of overhead downloading an SVG image over and over
again involves.

As for question 3, it's a bit too generic for me to be able to answer.

Firefox SVG support is slowly (almost) becoming usable. I wouldn't call it Good yet.

Hmm. A Wiki takes you 90% of the way there, Wiki's version and share txt, SVG is just text.

Inkscape is a marvelous really Good SVG drawing app. I heartily recommend it. http://www.inkscape.org/

Subversion is another Good way of sharing and versioning and displaying data on the web. www.subversion.org
