This is probably a bit late. You may already aware that some Autodesk products now Citrix ready. And Autodesk also develop Project Twitch that allows you to have a product trial without having to actually install the product. I found this quite interesting. Today, you need to install several GB of installer to your hard drive. If you can’t get the trial DVD from a reseller, it’s worse. You need to download the installer. If you don’t have a good internet connection, it will be very annoying.
At the moment, only AutoCAD LT that looks ready. If you go to Amazon.com, you can try the product online.
Scroll down the product page until you can see special offers and product promotions. You can access the online trial there.
If you read the Project Twitch description, I believe we can expect to have more online products trial in the future.
Unfortunately, the online trial seems to be limited by geographic location. If your location is allowed to access the trial, go ahead, give it a try!
