Hi,

I've coded a software packet shaper package for FreeBSD 2.2.x
and FreeBSD 3.2 recently.
Now, i would like to introduce it into the FreeBSD-net community,
for beta testing. 
(Hopefully, I'll contribute the code to the current...)

[Features]

 - a process-oriented software packet shaper,
   on which you can limit network output of any process

 - very little packet classification overhead
   and almost no impact on max throughput

 - provide bandwidth control without hardware,
	e.g. ATM card, or shaper boxes

 - works with ALTQ (tested on FreeBSD 2.2.8)

 - shipped with useful bandwidth management applications
   for easy control over network output

 - netnice command (works similarly to nice and renice)

	% netnice 128Kbyte/sec 123

 - Enhanced sh (sh with bandwidth control feature)
	(maybe useful for scripting)

	% ftp www.foo.bar @512KBps
	% rcp /var/log/access.log archive:/var/hoge @32KBps 

 - Enhanced inetd (bandwidth control over network services)

	%cat /etc/inetd.conf
	ftp     ... /usr/local/libexec/ftpd ftpd -l
	telnet  ... /usr/libexec/telnetd telnetd @32K/sec
	shell   ...  /usr/libexec/rshd rshd @32K/sec
	%inetd -c 10 @512KB/sec

	(In this case, telnet and rsh sessions will have 32KB each,
	and ftp sessions will be granted the rest of the available 
	bandwidth fairly.)

 - bandwidth control module for Apache (mod_netnice.c)

I believe that this is quite useful option to control LAN bandwidth
for sites suffering from huge volume of traffic for log file and
netnews transfer. It's simple, and you can have control over them
without any hardware assistance.

Thank you,
