You really don't want to run Sprite on a single host, unfortunately -- the local filesystem path is buggy, and there are some major bugs in the system as preserved on the CD-ROM, e.g. vfork() is totally borked, at least for software which expects a BSD-style vfork.

With some fixes, it can be pretty stable. Here's a web server running on Sprite on an IPC: https://ember.shockfox.net/

Or, well, it is running right now. I don't leave it online 24/7, so caveat emptor to future visitors.
