I concur, Salva, that this is the approach I need to take. I'm more inclined to use Net::OpenSSH as it seems the most portable (and, as was pointed out by Krambambuli below, all the other modules are wrappers to one degree or another for external binaries). In my response below I distilled the issue down to "How do you make DBI connect with DBD::mysql over Net::OpenSSH tunnels ?" and I suppose that's the crux of the challenge.
