Need more space for CASApy PPA

Hi

I am putting an upstream binary from http://www.atnf.csiro.au/computing/software/casapy/
in order to have easy installation and automatic updates.

The package is small enough to fit i386 and amd64 into a 2G PPA, but I cannot get the next
upgrade in due to too little space. Can the PPA be doubled to 4G please?
