How long will yeast last that you saved from a previous batch?

It should be good for several weeks, possibly longer I'm sure.
If you want to hold it longer, it might be good to make a starter and "revive" it, then refirdgerate the slurry again. (I'm not sure I'd bother: I'm about to pitch a couple slurries that I have no plans to use anytime soon.)

I've gone up to 3 months, but not longer. I've got some 1056 that is more than 6 months old that I might try and revive as a science experiment.

IMHO, the length of time a yeast will survive depends on the sanitation procedures used.
In the end it all comes down to smell and taste.
It's logical that if you reuse a yeast from week to week that it'll stay viable longer than something you used 6 months ago.
As for store purchased yeast I have used yeast that was expired over 1 year. I just had to make a starter a couple of days sooner, but they worked fine.

Thanks for the input.
I was going to get a small collection of yeast strains going, that way when I brew a belgian dubbel then I can use the proper yeast from a previous batch... so i'm not forced to use the same yeast in every batch.

I have a bunch of different yeasts in my fridge, both liquid and dry packets.
