To pursue the 8x8 train of thought a little more, I'm wondering how investors can leverage the emergence of VOIP. Do they take advantage of industry growth by pursuing companies in the hardware, software, security or service sectors? If so, do they stick with well-known brand names such as Symantec, Juniper, Cisco and Nortel, or are there interesting niche players out there? Any feedback/ideas would be much appreciated - not from a personal investment point of view but in terms of getting a better handle on whether the investment opportunities out there come anywhere near the hype surrounding VOIP.
