Question : Comparsion between VNC viewer and Teamviewer for Corporate Use for a Proposal

I am trying to write a proposal between Tight VNC and Team viewer for corporate use.
I am trying to write an indepth report on the how it will be used inside the corporate environment and also outside, when our clients are offsite and at home and not connected via VPN or wireless card to the companys network.

I want to know what sort of encryption is going for both Tight VNC and teamviewer.
Look for the pro's and cons of both pieces of software.

Long term affect, will it hinder our clients or enhance the experience and give them more support.
We have alot of moblie workers, that go to the clients sites and sometimes unable to connect back to the network, so remote support is no go and have to advise our staff, they need to come back to the office to look into this matter.

If we used Teamviewer we can connect when a internet connection is avaiable and seems more user friendly.. I am looking for information on all aspects so i can give a informed decision and proposal for long term and pushing forward to flexiablitly ...

if you could assist and guide me with information or point me in the right direction would be eternally greatful

Maybe the following site may help:

http://en.wikipedia.org/wiki/Comparison_of_remote_desktop_software

There do seem to be VNC versions that use encryption according to that (I was originally thinking of realvnc and tightvnc, which don't).
