Improved user experience transferring from APF to webDAV volume

Question

We've all experienced how files that we drag from our Desktops and drop on folders on the same volume are "received" at their destination and "lost" at their origin. They move.
Users in my organization desire a similar experience when dragging files from their Desktops to folders NOT on the same volume, particularly remote volumes; or ones mounted using a different protocol, like http (webDAV to be exact)--whether on same volume or not. They prefer not having to dispose of needlessly remnant files on their Desktops.
I'm responsible for providing a solution that delivers this experience. I suspect this will require an Applescript.
I have written one that is basically functional. It calls a handler within a folder action to delete files still selected after copying of them to the attached folder completes.
I include my script below. My interest in posting here is twofold.
First: maybe someone can help me make this script work better. I'm still learning, and I haven't gotten it to handle important cases properly.
Second: I wonder whether this has not already been done. I've looked at MacScripter, Applescriptsource, Apple Discussions, and certain individual scripters' sites; but keywords I've come up with haven't gotten me results.
In advance and for any assistance, thanks!
Here is my script. I know it fails if I get an overwrite dialog as a copy operation begins.
If in the Finder, deselection occurs or selection is changed as script runs, no files or wrong files get deleted. I've also had the script delete a file that never got copied to its destination when a permissions dialog came up.
I'd rather no one actually run this script. Just examine it.
The script gets attached to a webDAV site's icon that appears on the Desktop once connection is made. This seems to work like a folder; hence my use of folder actions.
That icon goes away if I disconnect, but I would need the script to work every time connection is made. There are probably other issues.

This OS behavior is there for a reason.
Good question. Thanks for noticing my post at all much less thinking critically on the subject.
webDAV site is to hold users' working folders. In our case, there will be a lot of dragging from Home folders (including Desktop) to webDAV.
The experience will naturally be compared with that of dragging files to the usual place for working files: a local AFP volume. Since drags to webDAV are going to fail by comparison on speed, I'd like to deliver comparability of the "move" experience.
What if your users want to copy (not move) an item to
a network volume?
As for dragging to other volumes, only the webDAV site would have the folder action. I should have made it clear: I'm talking about getting this functionality only in the case of users accessing their webDAV-hosted working folders.
I can understand readers thinking my aim was to change OS behavior. My fault, the vagueness on this point.
Anyway, Cyclosaurus, don't get me wrong. It relieves me know about the command-drag feature--that's great!
