Actually I'd like to see the tfc version of 2mesa4 ported over. There's a couple extra passageways it has that 2mesa3 doesn't have. Botbusters server has it on their server if you want to find out what it's like, if you have TFC.
Edit: here's a tfc demo I recorded to show the extra passageways on 2mesa4.
