For road machine, you need to use DHCP and VPN for security.  I use the 
office VPN from a windows box.  Why VPN, simple, a low end packet 
sniffer can in the course of a few hours at a hotel, capture over a 
hundred user names and passwords.  VPN will foil this.  Use the office 
VPN because your down speed will be the same as the up speed of the 
network you VPN to.  Also, if said hotel has a port in the wall, 
remember they are most likely using hubs meaning that everyone can see 
your network traffic, just like wireless.

In short, never go anywhere on a public network without first using a 
VPN service.  Consider doing so like running around town naked.  I have 
no clude how an eCS computer can successfully VPN to a windows network.

As for static IP addresses, some DLink routers and possibly some others 
can be setup to always assign a particular IP address to a particular 
MAC address.  I have a linksys that can't do that and a wired DLink that 
can.  This way, you can assign a static address to your computer but 
still connect using DHCP.

My router desires are...
    Wireless G
    VPN pass through (Very Important!)
    QoS   (Very Important!)
    MAC ->particular IP
     can set up an internal computer as the first DNS server

I run a DNS server here because at times, my ISP is SLOW.  It checks 
once per day.  My linksys  router can do this.

IP address to particular MAC, my Dlink has, my Linksys doesn't

QoS is Quality of Service.  The Linksys has that.  This is needed if you 
use Digital Phone and it is not the outside box (Vonage routers don't do 
VPN which I need, it's in the menus but even vonages as is just 
decoration.  The idiots claim none of the customers need it).  When you 
are downloading, QoS can prioritise the phone traffic.  If you don't 
have this and you are in the mist of downloading stuff (podcasts, 
bittorrent, big images files etc), then the person at the other end 
can't hear you.  So, QoS is required cause when you are on the phone, 
all other traffic needs to take a back seat.
