[Agda] Windows/Linux versions of Agda

[Sam Staton]

Something I thought of in the past, as a way of getting people quickly 
using Agda on their own non-linux machines:

We could produce a disk image of a small linux distribution with Agda 
and emacs preinstalled. This could then be easily and quickly run within 
virtualbox (which is free) or alternatively booted from a usb stick or a 
CD.

I think it is quite easy to make a disk image like this.

Sam.

PS. By the way ... iOS? Do people run Agda on iOS?
