I never published this one, but there was some recent interest. I hope it's helpful:

It explains how (and why) to send data back and forth between server and client apps, so that multiple users can work concurrently with a single persistent series in the memory of the server computer. Basically, it extends the idea of simple block manipulation, so that blocks can be used to build multi-user apps which typically require a network based RDBMS such as MySQL).

I'm wondering what would be involved with writing an isam database and using record level locking rather than locking and unlocking the entire database rapidly as you do here.

A table of record keys, containing the keys of locked records?

If you're interest in database work with Rebol, here are some other implementations and interfaces:

There's also https://github.com/rebolek/prot-redis and the new mysql implementation for R3 at https://github.com/kronwiz/r3-mysql

I have used the one written by niclasen. It's nice. Does he have a multiuser implementation for it?

The author has created one for his own commercial use. Check the response by user Geomol in the "Ann-Reply" group of AltME. You can contact him privately there.
(You could also roll your own network interface)

Thanks very much Nick, very helpful.

Thanks for all the suggestions. I have been unable to get any response on altme. Is there something I am missing.

Did you send a private message to Geomol, or are you having trouble sending group messages?

Sorry, I'm absolutely clueless on this whole process. I thought I was supposed to visit a world but I can't if I don't have a username and password that is valid for that world. How do I send messages to Geomol?

I can add you to AltME:
