If the processing is considered "offline" and not latency sensitive, then you can put that work onto a task queue and take up to 10 minutes. No need for a backend.
As for SciPy, Brandon is exactly right. SciPy is written entirely in Fortran whereas the other third-party libraries we have (NumPy, PIL, lxml) are written in C. For NLTK, do you really need SciPy? According to nltk.org, only NumPy is a dependency (optional). On Monday, 23 July 2012 09:33:35 UTC+10, Hans Then wrote: > > Ah. That is very good news. We have no real timing requirements.
