The Berkeley BOINC framework can be pretty easily adapted to do this.

Off by about a factor of 100 there. RSA-2048 is roughly equivalent to a
112-bit symmetric key; RSA-1024 is roughly equivalent to an 80-bit key.
32 bits of difference equals a factor of four billion. It's way harder
than you think.
