I don't know the current implementation, but I'd imagine the following:
- if the file is local, open that file directly with KConfig
- if the file is remote, download, open the downloaded file with KConfig

Everything is done the same way from this point on, except that there 
are writes/actions  that trigger an upload, in which case 
an "uploadProject" method is called which uploads if it was a remote 
file (or let's say sync-s in case of local ones).

I don't see the need of unix signals. Quanta has a crash-recovery 
mechanism since quite some time for documents, and a similar could be 
used for projects as well. The idea (in a simple form) is something 
like the following:
- keep the downloaded file in a separate temp directory
- keep a list of what project was opened in kdeveloprc (or some other 
config file)
- when the project is closed, remove the entry from kdeveloprc

If KDevelop crashes, the entry from the kdeveloprc will not be removed, 
so on the next startup it knows that there is a downloaded project 
file, which can be used to recover and go on from the last state 
instead of downloading an older version from the remote place.
