rsync - Dec 2004 - SUGGESTION: rsyncing gziped source with non gziped destination

Would it be possible to make rsync capable to sync gziped source (at server) 
with non gziped detination file?

PROBLEM:
The rsyncd server provides a few *frequently* accessed, slow changing, *big* 
text files (DNS RBL zones).

It seems that the source files are too big to stay in memory caches and rsync 
sessions cause to many hard disk I/O operations. Making rsynd capable to 
"ungzip" the files "on the fly" may help to fix the problem
by reducing number
of I/O operations.

You should think again about this. About the general "server quality" 
consequences for rsyncd, and about the efforts for your special case 
(=none, even contrary).
Add more RAM to your server and/or improve your I/O throughput.
