Replying to myself here because I forgot to mention that the benefit of the 
hideous connection string is that it requires no modification to your 
TNSNAMES.ORA file (I believe the normal way of connecting to a remote DB is 
to specify a certain name that you've configured in TNSNAMES.ORA).

The above is particularly important if you don't have a true Oracle client 
installation (IIRC last year I posted a list of just the files you need to 
make DCOracle2 work without doing a full Oracle client install - on Linux, at 
least for me, the Oracle client install was massive, scary, and flaky).
