One question that has been coming up at the back of my mind for the past several weeks has been how difficult would it be to create a collaborative multi-user online virtual world application in Haskell. More specifically, last August, I came across a very interesting application called Croquet (see http://www.opencroquet.org/index.php/Main_Page), which happens to be based on Squeak (see http://www.squeak.org/), a dialect of Smalltalk. Croquet, in turn, provides the basis for Cobalt (see http://www.duke.edu/~julian/Cobalt/Home.html), a "virtual workspace browser and construction toolkit for accessing, creating, and publishing hyperlinked multi-user virtual environments" (according to the home page for that project). What struck me as especially interesting was how Croquet allows multiple users to collaborate together in a multi-user online virtual world in software development and other collaborative projects. As one application, the video clip on the upper-right-hand corner of the above-mentioned Croquet home page illustrates how a user can, by writing code from inside the application, create on-the-fly additional virtual environments, which can then be entered by either the programmer or other programmers. Other applications (shown in other video clips on the "Screenshots/Videos" page (see http://www.opencroquet.org/index.php/Screenshots/Videos) show alternative applications that include text-based annotations, a 3D spreadsheet, and writing a conventional blog from within a virtual world. Unfortunately, Smalltalk is an object-oriented language. If possible, I would like to see something similar in a functional programming language such as Haskell. Does anybody know whether duplicating this project in Haskell would be feasible? -- Benjamin L. Russell -- Benjamin L.
