I think that it is much easier to use a pipe or a fifo, but I do not know 
the windows world. 
 
Is this what you meant?

------------------------------- cut process.pl ---------------------------
#!/usr/bin/perl
use Net::HTTPServer;
use Template;
use strict;

#setup template
my $config={
     EVAL_PERL    => 0,               # evaluate Perl code blocks
};
my $template = Template->new($config);

#start http server

my $server = new Net::HTTPServer(port=>5000, docroot=>`pwd`);
$server->RegisterURL("/process",\&go);
my $port=$server->Start();
print "I'm running on port $port\n";
$server->Process(); 

sub go {
  my $env = shift;  # hash reference
  my $templ=$env->{template};
  my $res="";
  $template->process(\$templ,$env,\$res);
  return ['200', {}, $res];
}
--------------------------- /cut -------------------------

and 

perl process.pl
mozilla http://locahost:5000/process?template=x:[%x%]&x=3

otherwise, I would suggest sending data and template to a pipe or fifo in 
yaml or xml format, and get back the interpolated data. 

hoping that this is python:

v = {
  template : 'the value of x is [%x%]',
  vars: {
    x : 3,
  },
}

v_str = yaml.dump(v)   

send v_str to a perl program, or dump to a file and call the perl program:


---------------------------- cut --------------------------
#!/usr/bin/perl

use Template;
use YAML;

undef $/;
$str = <>;

#setup template
my $config={
     EVAL_PERL    => 0,               # evaluate Perl code blocks
};
my $template = Template->new($config);

$v = YAML::Load($str);
$tmpl=$v->{template};
$template->process(\$tmpl, $v->{vars}, \$out);
print $out;
---------------------------- /cut ----------------------------
