[Arjen Markus] (2 may 2007) Now that the Wiki is (almost) back in its former glory, I had
a wildish idea about using the server it runs on for more Tcl applications.

Not hindered by much knowledge of the technical difficulties, I propose:

   * "We" implement a mechanism to run other Tcl applications 
   * "We" use the Wiki as a repository for Tcl plugin demonstrations and more serious applications

Just to make it more concrete:

One possible application could be to make some of the Wiki entries interactive. Take for instance
a page like [Fun with functions]. Rather than a static picture and a lot of code, the page could 
show a graph and a few entry widgets. You enter a few data, press the refresh button and there 
you are: a new graph for the new function or range.

More elaborate applications are possible too of course. 

(Enough for now, this is the basic idea)

[RS] Um.. somehow this goes in the direction of remote Tclets - without [Tcl/Tk Tclet Plugin]. As I wrote [Fun with functions], let's consider what would be needed in that case:
   * an interface where new user input (a string) would come in
   * the function graph is rendered on a canvas, so we'd need a screenshot (using [Img])
   * This requires that the app is on-screen, and not covered by other windows :(
   * If that can be assured, making a screenshot and serving it to a designated image file (GIF or JPEG) is a matter of a few lines of code
 set im [image create photo -data .c] ;# or whatever the canvas is called
 $im write $filename -format JPEG
 # notify Wub that it can refresh the served page
