Yes, the desktop client >= 1.3.0 implements what we defined here:
   https://github.com/owncloud/core/wiki/spec:-big-file-chunking

The functionality is very well encapsulated in a C lib, so if it is 
possible to enhance the software you're talking about it might be 
considerable to implement a direct upload to ownCloud in there.

Apart from that, I still think it would be good to have a commandline 
client that would work on the same settings as the desktop client, not 
sure if the recent python approach is still active.
With it, you would type:

$> occmd put huge_file.dat my_huge_files

and it would upload the local file huge_file.dat to the directory 
my_huge_files on the configured ownCloud server. Should be fairly easy 
to implement (C++, Qt).

regards,

Klaas
