Well.. This is why I prefer RAdmin client (www.radmin.com). Secure enough and pretty low network load (depends on what refresh rate
you set).
However, when it comes to remote working RDP takes the lead.

With 10-100 machines that would probably be the best approach.

Adobe Reader is not big app but would bring some dependencies in your image.
However, if you are planning to go with Terminal Server, wouldn't that be easier for you to just have all the files on the server
where users can access them during TS sessions? I mean they just start the Reader app on the server remotely.

That would completely depend on the functionality you are looking for the image.
In case you want a simple thin client image with network stack, IE and Adobe Reader included, you can accomplish that with the image
size less than 128M. (giving your numbers I have seen with my own similar images)
