The way that rsync uses hashes isn't at all problematic.  If an attacker 
has the level of access to be able to introduce hash collisions into 
files that you're copying using rsync, then you have bigger problems 
than the hash collisions!

In my opinion, rsync isn't a wheel that needs to be reinvented using 
LiveCode. :-)  However, yes, since rsync is almost entirely constrained 
by IO bandwidth, there's no reason that you couldn't rewrite it to be 
fast enough using LiveCode.
