rsync for PDAs?

I've been working for the past few months with open-source solutions for 
syncing Palm PDAs (Coldsync, mostly).  I've been becoming increasingly 
annoyed with Palm's Desktop Link Protocol and the sync mechanism, and am 
considering replacing it with a third-party application for the Palm.  Since 
I've had good luck with rsync in the past, its seemed an obvious choice.

I've read over the technical documentation and the algorithm looks like it 
could be implemented on a 'small' system.  (In this case small is roughly 
20mhz+, with very little RAM available on top of that used for storing 
files.)  However, theory rarely reflects reality.  My question is for anyone 
who has experience implementing rsync: how processor/RAM intensive is it 
really?  Is this a pipe dream for resource reasons?

(Now, I'd probably be using a slightly modified rsync, because files in PalmOS 
aren't flat files, but rather record databases.  However, that'd just mean 
the software should be record-aware, but probably won't require a lot of
