Assuming you have a laptop, why not just install whatever you want on
it and point your browser to http://localhost/mybigfatmaprepository/

I have MapServer, Apache, PostGIS/PostGres, Perl, PDL, OpenLayers,
jQuery and just about everything else installed on my 4.5 lbs MacBook.
I have a little snippet of code in my application so I can turn Google
Maps "on" or "off" as needed before I even launch my programs (I use
Google Maps terrain maps as a base layer). I even have the
documentation for all these programs installed in html form, heck,
even minicpan. No need for Internet at all. The only thing I can
continue to have is unlimited power, but as long as I can turn my
computer on, I can get to all my data. No Internet, no x.5G, no
