Just don't expect to be able to make good beer with it.
I'd disagree - I've made a best bitter with a British bread yeast (Allinson's - may well be a white label of Lesaffre but I don't know) and I'd concur with the "pretty good" comment above - not my finest but a solid 7 or 8 out of 10, friends would be more than happy to drink it.
The thing with bread yeasts is that they tend to not have all the fancy enzyme genes so don't have great attenuation and are generally POF+ so produce Belgian-style phenolics - but in my case they were pretty mild, nothing like the full-on saison thing. Think something like T-58. Dropped better than I expected as well, although flocculation wasn't great.
Would probably work for mead or cider, but I can't guarantee the result, it's worth a try though.
And if all else fails then you can use it as yeast food - the great thing about cannibalism is that you know all the nutrients are in the right proportions!
