How safe and feasable is it ?

Hi list

Here's something I've had in mind for quite some time.
Let's say you have an app built with LC that you send to
various users as standalones with regular updates.
What if all the most important functions of that app were
gathered as handlers in the main stack script for instance, and
at every startup, a script would check with a remote server
for a possible update of that script, and dowload the new
version (if any) to replace the old one with a simple
"set script of this stack to myVar" ?
The standalone could be a simple front end with all the
most important objects, and therefore would weight slightly
less than the complete app, and above all would need to
be downloaded only once by end users who would not have
to worry about versions and updates.
At first glance this looks like a convenient way to update
existing functions, add new ones, manage different settings
among users, etc.
But what about safety ? Is there a way to encrypt the main
script while it is downloaded at startup so that it can't be
caught by some sniffer ? And is there any other crucial
security issue that didn't cross my mind ?

There's the part about standalones not being able to save themselves to disk. To make this work, the scripts would have to be in a separate stack that is put in use. If you're doing that, you may as well just download the whole stack and overwrite the old one. The only advantage to getting just the script itself would be if the stack is very large due to images or other content, and the only change is in the script. Then it would be faster to just get the text.
