Im glad to hear there's some interest.
Thin clients- we have around 70 terminal servers for somewhere in the region of 2000 thin clients.
Web development- we do as much as we can in house, our web guy does a lot of programming in ASP and PHP. We use MS SQL 2005/2008, clustered.
VLE- we currently use Blackboard hosted in-house but are looking at other options such as moodle.
Wireless- we have two cisco lan controllers, one at both our main campus'. These serve around 100 ap's.
Remote access- the only remote access we currently offer is webmail, extranet, and RDP.
I'll let everyone know the date when I can finalise it. It's been a very busy past couple of days as we're putting in a second Cisco 6509 core switch running VSS, this will be a very big part of the day!!! Oh and 25,000 users, you can tell its been a long week!!!
