integrating rsync with Rev

[Josh Mellicker]

I'm working on a project that requires robust downloading abilities  
that include syncing remote and local directories, checking for newer  
files on the server, and compressing files during downloading to speed  
transfer.

I have written this code in Revolution but I'm not altogether happy  
with some aspects, notably the fact that "background" downloading via  
libURL is not completely in the background, slowing down  
responsiveness, and even missing mouseUps at times.

Luckily, there is a GPL'd shell app called "rsync" that is amazing! It  
does all this and much more, including the ability to only transfer  
the changed portion of files! (something it would take a while to  
script reliably in Rev and would need a serverside counterpart)

Has anyone worked with rsync? I feel anyone using Rev to upload/ 
download/sync files should investigate using rsync in lieu of commands  
like "libURLdownloadtoFile", "put" or "load".

Anyway, rsync is easy (from Terminal), but I am having a hard time  
getting started with using shell commands in Rev.

So, I am asking for help, of course, any suggestions via this list  
greatly appreciated, once I get it working I would be happy to share  
my stack.

If someone is excited about integrating rsync I would be happy to fund  
this effort for the benefit of the Rev developer community.

Thanks for your input.
