SMP will be supported in the next version of xz. And yes, it takes a long time 
to compress openoffice. On my old PC it took 4 minutes to recompress. But 
package size went down from 166MB to 124MB. So, unless you can upload with 
more than 316 KByte/s (I hope I got that right ;-)) you are still faster. (and 
I know that your PC is a lot faster than mine)

So even if you only take your own time into account you still win. Adding the 
time/traffic decrease of all mirrors and users to our calculation we will 
clearly win.
