uoamhub is a dedicated server for UOAutoMap. UOAutoMap is written by Steve Blanding, and is an explicitly non-free map tracking tool for Ultima Online, which has networking features with a proprietary, undocumented protocol.
The binary is around 25 kB, and it needs about 600 kB of RAM. The server consumes a few seconds of CPU time a day.
There is a demo server: uoam.sassie.org:2000, password "th" (or any other password).
The current version of uoamhub is 0.9.1.
The uoamhub sources are managed in a Subversion repository. You can view the repository in your browser, or check it out if you have a Subversion client:
