V-FONS

Has anyone tried one of those vonage v-fons with a laptop and pcmcia
card?

I have a stable "good" connection on a P150 laptop for internet now.
Using only a good firewall and no router on this one computer
connection. Connection is on a channel not shared by others (site survey
shows only transmitter on that channel), but my connection speed seems
to vacillate alot. Using Tor for security, so maybe that's part of the
speed variations I'm getting. Vonage says I only need 90kbs connection
for the vfon to work with a router. I have not measured my data speed,
am guessing it is probably around 5mb/s. But this varies from very slow
to 10mbs according to my firewall.

They also claim the vfon works on a usb port on win98se with no separate
drivers needed. The fee for the phone and startup is around $100 and
they CLAIM they will refund it all if returned if cannot get it working
in 30 days.

Anyone give me an idea if the vfon can make a fairly dependable
substitute for a landline phone in such a case. I am probably dreaming
:-).

Grateful for any good replies on this, thank you.
