Great thread, thanks to all!
I and a few friends are very interested in doing a modern MUD-style text et al virtual reality server in Pike (or another modern interpreted language) supporting AJAX, telnet, and a browser-based OpenGL rendering layer (probably in Java, JRuby, or Flash, etc).
We are old LDMud & MudOS guns with a bit of experience in C and Java looking to enter a new interpreted Multi User Dimension through a Web 2.0 wormhole.
As has been wisely said modern Pike Muddery would be well-served by coretight library running in a sandbox with MUD-style network handling, filesystem emulation, user security system, world environment and object management, various user communication and object-environment interactivity.
We are looking to create such a library for a modern MUD-core implementation in an industry-grade framework. Pike is certainly one of our considerations.
I would love to know the status of any such Pike or related framework projects anyone might know of or be working on. We are looking to collaborate, learn, or just discuss. Many thanks!
