You can use your OS's QOS handling for that, just place your important 
outgoing packets in a high priority queue and the rest (including 
eDonkey traffic) in a low priority queue with a restricted bandwidth.
I've set up such a system and my pings rarely are above 100ms.
A  ping to my ISP shows :
...
20 packets transmitted, 20 received, 0% loss, time 19207ms
rtt min/avg/max/mdev = 60.007/93.442/157.413/28.221 ms

With no network load, the min latency with my ISP is around 55ms (so I 
only lost around 40ms here).
You could tune the script further (I didn't bother as I don't play fps 
online, this is tuned for ssh sessions and network go games...) but IMHO 
a max of 150ms with an average of 100ms is a good start.

If people are interested I can forward my setup scripts to them or the 
list (for Linux 2.4 kernel based distributions).

You could call "nu" with a netcat script too, didn't try that.

Same here :-)

# Download / Server connection pb

On a different topic, this is my current cs output (2.02-9).  Upload 
average is quite low, but this is probably because mldonkey was 
recomputing md4 hashes (done a recover_temp that last several hours). 
Download is very low since a week (although ~200 files in downloading 
state with some having hundreds of sources).

I've tried nearly everything from 2.02+pango to latest current cvs and 
always allowed for one full day runs without restarting mldonkey with 
each version.
Catching servers seems near to impossible too although :
- all udp/port used by mldonkey open (tcp 4662 / udp 4666 / tcp and udp 
20438) system directly connected to the Net with a static IP,
- server_connection_timeout = 30 (was 5 before),
- force_high_id = false
- master_server_min_users = 0.
- max_connected_servers = 3

mldonkey seems to search servers on startup but stop to do so after a while.
