In my HL servers i have a mm plugin that enables old style bunnyhop. It also requieres a modified client.dll clientside to allow smooth bunny hoping wich i think it came from previous HL versions.
In linux there are no previous version, so there is no bhop patch.

I was wondering if there is any possiblility to add a sv_bunnyhop cvar so you can enable/disable such feature in a server easily.
