If you call sshg3 while the SFTP connection is open, it would send the command through it (well, IIRC, unless you tell sshg3 explicitly to not do it with the --exclusive option).

Also, the development version of my other module, Net::SSH::Any, has a backend for sshg3:

use Net::SSH::Any;
my $ssh = Net::SSH::Any->new($host,
                             user => $user, password => $password,
                             backend => 'Sshg3_Cmd');
$ssh->error and die "unable to connect to $host";

my $output = $ssh->capture('ls');

Unfortunatelly, at this point, Net::SSH::Any integration with Net::SFTP::Foreign is broken.

Do you have a time frame on the release of your development version? This looks like a perfect solution for what I am trying to accomplish. It is frustrating that even though the SFTP connection opens a sshg3.exe process I cant make normal ssh calls with it. Thanks for your help.

Not really, I work on Net::SSH::Any mostly for fun on my quite scarce spare time so, I can not commit to any time frame.
