I realise that you guys are discussing network control, but if your treo has IR capability (I know the Lifedrive has) you might like to try Novii remote.
OK, its not free, but once you have designed your layout and gone through the teaching process, not only will it work the SB, but also your amp, tv, DVD, cable etc, etc,etc.
As long as you can point an IR remote at it, it will learn it... even IR controlled cars!
SB1001+ NSLU2 + Firefly svn-1568 + Maxstor 3200+ Amp= alot of clear shelves where my CDs used to be!
If at first you dont succeed... buy a bigger hammer!
