questions of MP construction

[TechnoMage of Shadows]

I have 3 live,
1 other live but on holidays (it won a free trip to vegas),
3 warm (ready to run, o/s installed and all equip. avail.),
3 non compos mentis (no ram for them - o/s & equip. avail. and installed),
otherwise i'd run an 8x lan to test.

will 6 machine/players desync??

and if i wanted to allow one/several of you to hamachi in, then exactly which configuration would i need to run?

- Hamachi on best machine and allow you to tunnel in?

- or hamachi on all mine and tunnel into my own lan??
(which would be deathly slow, sending and recieving my own traffic...)

- or hamachi all mine and tunnel into your lan?
(again my wan link would be busybusybusy)

quite happy to run a solo "sixer" lan If you think that will desync, will NOT have time to do that for approx 20 hours
