Re: [Bug-apl] Ideas for an online demo-version of GNU APl

[Juergen Sauermann]

Hi Thomas,

nice idea, we should try that.

I believe that it should already be possible to start
GNU APL from eg. an apache web-server; the missing
piece could be the backward direction (user input -> webserver).

Security should not be too hard on linux systems.

A problem remaining is where to host this in a permanent fashion.
Probably the GNU project will not be too happy if we use their capacity
for (possibly heavy) APL demos.
