Hi Tom,

Good luck in the new job.  I taught for a little while at Lanier Tech 
and was just getting into the online learning technology when my 
assignment ended.  I've also been doing some research into online video 
and audio conferencing for a private mini online learning project I want 
to do with some associates involving learning Java.  I've gathered a few 
links that might be useful to you, while not specifically about file 
formats and such, they address some of the needs you'll face with 
distance learners.

If the school is a Windows shop, then I'm sure they don't want 
additional expense or problems based on the introduction of Linux or Mac 
technology.  That doesn't mean you can't use those technologies, but it 
does mean your solution has to be seamlessly compatible with and 
accessible from Windows.  Also, most of your remote users will probably 
have Windows PC's at home, unless the school issues Macs or something.

Regarding robustness, Lanier Tech used a very interesting technology 
which might be helpful to you.  It's a product called Deep Freeze, from 
Faronics.  They used it on all their computer workstations.  Basically, 
the product completely locks down a user workstation.  Once it's set up 
to a desired configuration and the other application software is set up, 
you "Freeze" the system.  This stores all the critical data and 
applications and configuration in a hidden spot.  Then, let the students 
have access to the system, in a lab, for example.  No matter what they 
do, whether they change the background, alter the setup, inject a virus, 
even delete the whole C drive, all the staff has to do it just reboot 
the computer and it's back to the way it was.  It's pretty awesome.  
This dramatically reduces the maintenance that the staff has to do.  You 
can unfreeze it to apply patches and change things, then refreeze it.  
Also, you have to make allowances for any new data you want to survive a 
reboot to be stored elsewhere other than the frozen drive.  It's mainly 
for workstations, but could possibly be used for a server too.  It's 
available for Windows and Mac, and is definitely not free, but very cool 
technology.  Their standard edition is about $35 / yr / seat.  They have 
enterprise offerings too.

For Linux, you might look into the ZFS file system, which, I believe, 
can do system snapshots to give similar functionality.  I know nothing 
about it, other than what I've heard on a few podcasts.  You might have 
to go to FreeBSD or something to make that work.

You're going to need some sort of web conferencing and web collaboration 
software, most likely.  Lanier Tech was using a system called Angel and 
a system called Elluminate, which you mentioned.  Unfortunately both of 
these have now been bought by Blackboard, so there's less competition.  
My (anecdotal) understanding of Blackboard software is that it's very 
powerful and very expensive.  If you've got the budget, it might be a 
good solution.

Blackboard's Angel system:

Here's an open source solution for web conferencing which some of the 
people here on the list recommended for my Java project.  It has audio 
and video conferencing and whiteboard capabilities.  It's probably the 
one I'll use.

Big Blue Button

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

Here's one of many companies that can run a Big Blue Button server for 
you and provide web conferencing and e-learning services so all you have 
to worry about is your teaching, not running the technology 
infrastructure.  Prices are very reasonable: only $ 25 / mo for 10 
people and $ 75 / month for 50 people with various levels in between.  
They also have a 5 person plan.

TeamViewer is another web conferencing software I've heard good things 
about.  It is compatible with with Windows, Mac, Linux, Iphone, Ipad, 
and Android.

I hope you find this information helpful.  Please post back here and let 
us know what you come up with.  I know I and probably others would be 
interested to know.

Sincerely,

Ron

(PS - If you email me and don't get a quick response, you might want to
call on the phone.  I get about 300 emails per day from alternate energy
mailing lists and such.  I don't always see new messages very quickly.)
