Does the ODBC or JDBC interface use compression?  I think these
are more likely to be used over a non-LAN connection.

The other use for compression would be for a data sync between
two database installations that are geographically distributed.The idea
is that two offices would each have a local DBMS but the link
between them is slow.  Compression could help in that case.

Compression is not all that hard to set up using port forwarding
proxies
like you thought.  In fact ssh can do it already if you specify the
"-C" option.
