No not at all Voics
I was just speculating probably a bit too much. (Thinking 'out loud' ?)
You're right with the AI crunch load... It would impose a bit on the hosting PC, but mostly on the CPU/main memory. Maybe today's dual-cores will fare very well?
I was just interested if anyone recently-ish had tried hosting AND playing any shooter-type games over broadband links with their mate(s).
I think I tried to hook me and my cousin together on Halo for PC a little while back (just for the helluvit), but the vagaries of the 'net connection proved a bit problematic. We connected, but I recall that it wasn't practical for real play.
Since then the higher bandwidth accounts like ADSL2+ might have improved things; I dunno...
