[ILUG-Social] Doom for Linux

[Ryan, Shane]

hi all,

I'm looking to get my hands on
either Doom I or II for my PC.
Unfortunately I cannot access 
IDSoftware's site because of
the silly web-filtering system
in place here.

Does anyone know where I can
buy a copy of Doom (which I will
be running on Linux...) online?
Last time I asked in Game they laughed
at me ;]

I would ask to swap for Linux software
but that wouldn't be ethical or legal.
Hence the purchasing question.

Regards,
Shane
