You can start the other erlang node with the option
-mnesia extra_db_nodes \[...\], telling mnesia to
fetch a ram-based data dictionary from the node running
yaws. Then, you can access all tables from the other node.
Search the archive for extra_db_nodes to see issues on
quoting etc. in different operating systems if you don't
figure it out on your own.
