have done this for a few laptops but besides the bit of extra key
management, which is doable, it does involve setting up the VPN client
which is a bit more challenging.
have used OpenVPN so far on some ubuntu laptops but also setting it up
on remote XP and Vista laptops is where it soon starts to become messy
was my thought.

my hopes were on a more centralised management without too many configs
on the local clients, one of the reasons we made it a web application
reachable by browser.

mmm, this feels like playing hide and seek and gamble on the odds, it
does have password protection but i'm not willing to rely on this alone.

problem would only be that with VPN ALL their traffic would pass my
server (correct???), this would lead to serious speed/performance
decrease for all other traffic for most of the clients.

VPN i guess you ment? it can work with a key AND a password (have not
implemented this tough since the laptops already have encrypted
partitions and strong passwords)

its surely appreciated,
