consider using PyPy with 'arm' where appropriate
I'm currently doing a lot of experimentation with Tor relays on single-board computers such as the Raspberry Pi. Currently, 'arm' is very heavy on such machines, taking a lot of memory and CPU.
It might be worth it to release a PyPy powered version if it results in significant improvements in speed and/or memory usage on resource-limited systems with ARM CPUs. Or, possibly, to build alternate packages for users of the Tor Project repos for Debian et al.
