I have been running LH-3.0 Beta on a Via-Epia 5000
http://www.newegg.com/Product/Product.aspx?Item=N82E16813181025

It's a 533Mhz Via EDEN CPU with 512+128 Mb Ram , running Ubuntu 10.04LTS
I was using /vs /gb /TW=25

It was running ok on that machine.

I have later invested in a "4 channel Serial to Ethernet" converter , and 
am now running 2 LH's from a 1.8Mhz VIA with Ubuntu 8.04 (my mail server)

These parms are appended at the end of the LH command line :
    /ip=aa.bb.cc.dd:4001/ /vs /gb /TW

The :4001 is the TCP port for serialport 1 on my converter.

This setup makes me able to connect LH from any machine to a TB.
But only one active connection is allowed at a time.

So in practice i'm running the 2 x LH against the TB's on the mail-server.
And "VNC to the mailserver" if i want to see the LH's.

But there were no problems using the old VIA-EPIA 5000 , i just have my 
mailserver on 24/7 , and didn't need the EPIA to be on when i got the 
Serial-to-Ether converter.
