(as requested repeatedly)
As the model portions do not update frequently at all, and those are all clients really need to play multiplayer, heres some zips.
http://nebtown.info/fastdl/addons/SBMP.7z (Feb 8th 2010 - v455 of SBEP_Entities, Fortifications, and Models)
http://nebtown.info/fastdl/addons/wiremodels.7z (Feb 8th 2010 - v2375 of wire model pack 1, also the nonlua from "wire")
These two are more optional, but will ensure theres no obscure error models.
http://nebtown.info/fastdl/addons/Nebcorp_Maps.7z (Every map on Nebtown's "extra files" like skyboxes and custom textures. Everything shipped with a map besides the bsp)
http://nebtown.info/fastdl/addons/Nebcorp_Collections.7z (All other models/materials/sounds the server uses. Includes "mariohat", "shark", and every CSS/EP2 tree >~:O)
These 4 addons emcompass all custom clientside content Nebtown uses. Map bsps will autodownload as required.
Contains all the SVNs (Wire, Nebcorp, PHX3, SBMP) presetup for you. Now contains Spacebuild 3!
Q: Doesn't putting SVNs in a zip file defeat the purpose of having SVNs at all?
A: No. Every day we hear of people who installed the addons wrong, simply because they don't know SVN. This is basically empty folders with the SVN data preset, all the end user must do is drag them to /addons and hit SVN Update. Which seems a whole lot easier, IMHO.
Also, as requested, some spawnicons for fresh installs.
If for some unholy reason you don't want to use our tidy zip, here are your direct URLs for SVN Checkouting:
