Well, I gave it 30 hours and then pitched the 860 which took off in 6 hours and is now done. You were all wrong.....

I still say you probably just didn't give it long enough. I pitched a Smack Pack of WY2000 dated early Feb around 8pm on Thursday into a 2.5 L starter. Saturday AM (T+36:00 hours) it still didn't look like anything was going on when I shook it up, but I could start to smell a little bit of fermentation character. When I got home Saturday night (T+48:00 hours) it was chugging along and foamed up heavily when I swirled it up.
I think that A) lagers don't tend to be vigorous fermenters and B) starters tend to be larger so the initial lag phase takes longer before you start to see visible signs of fermentation.
