Quickest way I can think of off hand ...
If your gamemode/maps/materials are released in zip format, take the zip, open it, and upload the
addons/<addonname>/materials , sound, map and models folders from it to the host.
I forget if others are needed.
If SVN, checkout to a totallly separate folder each SVN you use, and then upload the same <addonname>/....
I just realized though, the lua cache folder won't know better. You'll need it entirely to make it easy.
Not a big deal though. Lua files are usually very small, so won't go much against your storage limits.
Clients will only download the ones needed.
