It shouldn't merge the files, just load them into two separate TopicMap
objects.

No, that wouldn't work - the properties are just for loading topicmaps
from files or URLs, so

tm4j.topicmap.1=http://psi.example.com/mymap.xtm

should also work, but thats all.

You would need to create two topic map providers, one to connect to the
remote server, one to connect to your local server and then use the TM4J
methods to copy from the remote to the local server. For a big map that
could take a while. You could use a UnifiedTopicMap backend to do the
merging "on-the-fly", but there are some restrictions on that (e.g. you
cannot update the merged map, you can only modify the remote and local
topic maps).
