[support] Importing large files uploaded via FTP

[Luke]

I am looking for the best way to do something reasonably simple.

I need to upload files which exceed the PHP upload limit (which can be 
raised, but on shared hosting 8-15 MB is usually the top).

The only way I know to do that, is through FTP.

So, if a user has a big file, he uploads it via FTP, but then has to 
attach it to a node.

My question is: what is the most efficient or simple way to allow a user 
to tell a node to import a file from a particular place?

It will need to grab the file, place it in the normal files area, and then 
delete the one uploaded via FTP.

I suspect I'm going to end up using some mixture of CCK and PHP, but I 
also can't imagine that I am the first one to need a solution to this 
problem, so thought there might be some canned solutions out there.
