Can DBI::Proxy servers be chained?

[daedalus]

Hi all,

A quick yes or no would be appreciated before I spend much time on setting 
up the second proxy.

If the answer is "yes", a quick example of how to modify my current dsn 
would be *very* appreciated. ;-)
( my $dsn = 
"DBI:Proxy:cipher=DES;key=$key;hostname=$hostname;port=$port;dsn=DBI:Oracle:xxx"; 
)

Thanks!
