G'day Alejandro,
Yes the files must be imported into Alfresco so that things like versioning, access control, and ILM can function properly. Those capabilities wouldn't be possible if Alfresco simply pointed to files that are outside its control (and note that this has nothing to do with the import tool - that's just how Alfresco works).
The bulk importer is the best way to perform this kind of import, and as you say it requires that the source file be locally readable by Alfresco. This doesn't mean that the files have to be physically copied or moved to the Alfresco server, mind you, just that the Alfresco server can read them via the filesystem.
So what I'd suggest is mounting those FTP servers etc. into the filesystem of the Alfresco server, and then pointing the import tool to that mounted directory. The import won't be as fast as reading from local disk, but if your network is good it should still be plenty fast enough (and faster than other options).
The tool will then take care to physically copy the data in those files into the Alfresco repository, allowing Alfresco to properly manage it (including via CMIS).
If mounting the FTP servers isn't possible for some reason, you could also implement a BulkImportSource that acts as an FTP client and have it read directly from those FTP servers. It would be great to see this code published as open source, if you decide to go down that path!
Cheers,
Peter
