I believe this is not fun :) Using libraries etc ruins the golf scent unless
strict description. However without investigating the tinyp2p which lacks
description what it exactly does, I came up with those:

# pps.pl server--returns file name and data by regexp from current dir
#!/usr/bin/perl
use IO::Socket::INET;
use IO::All;
my $sr=$sock = IO::Socket::INET->new(Listen    => 5,
                                     LocalAddr => 'localhost:9999',
                                     ReuseAddr => 1 );
while(4)
  {
  my $cl = $sr->accept() or next;
  $re = <$cl>;
  chop($re);
  my @f = grep /$re/, <*>;
  my $n = shift @f; 
  my $d < io $n;
  print $cl "$n\n";
  print $cl $d;
  }
# 400 bytes approx.

and

# ppc.pl client--requests file by regexp and save under the server-offered name
#!/usr/bin/perl
use IO::Socket::INET;
use IO::All;

my $cl = IO::Socket::INET->new(  PeerAddr => "$ARGV[0]:9999") or die "connect 
error\n";

$| = 1;
print $cl "$ARGV[1]\n";
$n = <$cl>;
chop($n);
$/=undef;
<$cl> > io $n;
# 200 bytes approx.


both are *FAR* from perfect, there are so many issues like security, 
redirection etc. but 
still a shot into plain client/server httpd direction :)))

P! Vladi.
