Doesn't every VPN? Oh, that's right, there's PPTP. Might as well be

I'm not familiar with the firmwares out there, but which VPN are they
using? I've done PPTP and I can promise you that although it can be easy
to set up and use in a windows-only environment, it is not easy to set
up _properly_ and use in a heterogeneous environment. Not to mention
it's insecure. IPSec is never easy, unless you are using proprietary
server/clients with default configurations which almost never fit in the
real world. IPSec/LLTP is even less easy to set up, and it's the only
supported windows configuration without a custom client. But I ramble,
let's look at just the facts.
Upgrade firmware for linksys: 5 minutes.
Upgrade firmware to another firmware that I've never tried before,
hoping that it doesn't mess something up and then reconfiguring the
router to do what it was doing before and troubleshooting the thing I
forgot to reconfigure: more than 5 minutes.
Install OpenVPN on one computer: 5 minutes. Copy config files from flash
drive and generate a shared secret (which was appropriate for this
site), 1 minute. Punch hole through firewall (when not confronted with a
crazy linksys bug): 1 minute. (don't forget we've also got a dsl modem
to punch through - with openvpn this is one udp port, other vpns require
all kinds of magic)
Install OpenVPN or setup pptp or ipsec/lltp, or any other vpn, on client
box: 5 minutes or so.
Find the stupid norton firewall on the openvpn server box that doesn't
call itself a firewall and hides the configuration interface, and
driving to the remote site and back: 1-2 hours. :-)
Draw your own conclusions. I've been around the VPN block, and openvpn
is the lowest "TCO" by far, but I've no doubt some of these firmwares
make it real easy to get a VPN up and running.
Man I can ramble.
