Great news for internet users, the technology that can help you surf the web privately has been discovered. It has been around for some time, but it has never achieved popularity than it has today. I am talking about VPN or virtual private network.
There is a huge misunderstanding here. For many IT professionals, retainers mean a certain number of hours of pre-paid manual labour. In my vocabulary, a retainer engagement means that clients have access to your brainpower, and when they have questions, you give them answers.

If you doubt what you should do right now, start small and then grow as you need to. This isn't a bad thing, necessarily, because VPN technology can be easily expanded at minimum expense when you compare it to the older point-to-point or dedicated lines that were involved in traditional wide area networks, or WANs.
WPA - WPA is the solution to all of WEP's security flaws. WEP uses one key to for all network traffic. A hacker can exploit this by using a network analyzer to capture the key. WPA changes the key with every data frame so once a hacker captures the key it has already been changed by WPA. WPA uses tools such as TKIP and AES encryption.
One of the things I like about WiTopia is that it is cheap. I don't need a vpn all the time, so I can just visit WiTopia whenever I need it and pick up a month of service for $6. Year-long plans start out at $50 per year.
And many IT companies, believing that this is the only ethical way of running a business, eat up this rubbish left, right and centre. Sadly, many of them later choke on it... unless they spit it out in time.
Well, we are not making much progress in telecommuting field. Good old UK was doing much better back in 2002 with telecommuting rate of 7.4% [6]. Another question is what is the percentage of workers who can telecommute without negatively impacting the business process? I did not try Google to find an answer to such a sophisticated question. What I see from my personal experience of IT professional, at least 50% of office work can be done at home. At my consulting job, I see some of my colleagues once in two weeks, if I walk by. Otherwise, I do my work glued to my computer monitor, exchanging information via email and internal chat system. We do remote conferencing and project management. I do it in the same way as many of you do every day.
Overall I think there are many more pros than cons for choosing ethernet for your voice/data network . We are seeing lots of improvements to Ethernet these days via various industry working groups ..... as well as evolving packet transport technologies such as MPLS-TP and PBB-TE. So the future of etherent looks even brighter.
