Just wondering if this would work:
1. GM creates a repository file of all images she has to use (literally just sticks everything onto one map, and then creates the repository)
2. Distribute a DVD with that file, to be placed on the same location on all of the Player computers, eg. "C://Program Files/RPTools/MapTool/..."
3. Campaign repository listed as "C://Program Files/RPTools/MapTool/..."
For people with very limited bandwidth, this would be very very very useful.
But is it currently possible?
Its currently not possible. But what you can do is run a webserver on each of the machines, and then put the resource files on that webserver. Then for the campaign site have http://127.0.0.1/CampaignRepos/index.tgz
(or where ever you would like to place it). (127.0.0.1 being loop back to local host).
Just remember to get everyone to start up the webserver on their machines before they connect and it should all be fine and fetch the resources from the local machine.
As for webservers
Mac OS X has a web server you just need to turn it on
Windows XP you can download (I think they call it) personal server, but you cant run that on XP Home or Student.
Windows XP you could also try something like savant
which I have heard is pretty easy to get running.
