Alex had some really exciting demos, and last I saw, things were pretty far from being ready for prime time. I'm not sure that these things have anything to do with eachother, though. My preference is to keep the single-user functionality more or less the same, and hook a new robust server structure into place for sagenb.org and other large multiuser environments. > >> (4) Use mod_wsgi and apache to make it scale massively. >> > > (4b) package nginx or lighttpd or something with Sage so that Sage still > comes with a webserver? This is a must -- otherwise, we lose the ability to use the notebook as the GUI. Nobody plans for that to happen. I've put up a page on the wiki about this project.
