WeVideo is a fairly new collaborative cloud based video editing tool. You can set up project users and groups and folks can contribute media and share editing tasks all within a browser environment. It was really responsive and handles HD editing and distribution by providing automatic proxy creation and will render the final HD movie in the cloud and then simultaneously deliver to YouTube and many other social media platforms as well as any FTP location. The basic account is free and then is priced from $7 to $80 a month depending on your final resolution, storage amount, numbers of users and other variables.
The new Epson Pro Z series features great brightness and contrast ratio, 6 axis color adjustment, as well as some impressive edge blending technology to put multiple projectors side by side. I saw this demonstrated and was really impressed. They also offer split screen presentation, multiple PC presentation wirelessly (up to 4 systems simultaneously which could be good in a collaborative lab) and wireless connectivity with the iPhone/iPad. Their prices range from around $10k to just under $20k for the new models.
