let's do the math:
1 million subscribers (my estimate, probably higher than that) x $25/month (on average, probably a little lower with all the plans they have) = $25,000,000/month.
i'm guessing their overhead ain't $25 mill a month.
dunno, hope they go far. love the service.
According to Wikipedia:
"Until recently Vonage held the most subscribers at 2.4 million subscriber lines"
They "until recently" part had to do with Comcast passing them with 5 million, not any statement that the 2.4 million had dropped.
