Right. I write code for L2TP LACs and LNSes, among other devices for my
day job; I have some experience in this area.

One might argue that any kind of system will be (at least somewhat)
unreliable if the network underneath is unreliable. :-)

My point wasn't a technical one; lots of people here are reportedly using
Jetstream et al for VPNs, and router-specific (eg. NAT) problems aside,
there appears to be questions about Jetstream's essential reliability.

As a Jetstream customer, I continue to experience many microoutages per
day, that Telecom while working hard on them has been unable to resolve.

I find this very disappointing, compared with my personal and professional
experience (my home DSL in California, for instance, which I use with a
VPN to connect to my office, is completely troublefree for months at a
time - barring power cuts).
