I am currently looking into web filtering. It seems to be narrowed
down between Linkwall and surfcontrol.

From what I've read and seen so far, surfcontrol requires a windows
PC, is that true? It also appears that it wants that PC on the public
side of BM? If so, isn't that risky? wouldn't it also make for
difficult remote management of it? (internal remote management)
