make it a network/web-based multi-user game?</span></font></p></div></div></blockquote><div><br>Well, I actually didn't have this plan, but that is a nice idea. Back in 2008 my thoughts were to use the mailing list for communication and someone would run the program.<br>
<br>If the graphics part is created "modularly enough", it should be possible to change the backend - one backend would be the machine itself running the game and the other would be a wrapper around a web socket.<br>
<br>Security is complicated, thought. The file defining the feeb's brain would not be allowed to have any internal symbol from the package :the-feebs-war nor to create or use any packages, restricted to the exported symbols from :feebs and :cl, and perhaps :alexandria. Timeouts would be used to prevent users from creating infinite loops, but any user would still be able to exhaust the memory (or the stack), now I don't know how to prevent this.<br>
<br>I'll only set up a server if there are enough users interested in it, though, you are the first in 2 years.<br></div><blockquote class="gmail_quote" style="margin: 0pt 0pt 0pt 0.8ex; border-left: 1px solid rgb(204, 204, 204); padding-left: 1ex;">
