   Ah, good hint, I found NFS at home, a project to factor large integers...
   There is also Enigma at home, but that is a bit old fashioned ;)

   I think I'll stay with Folding at home

  Ok, that's even better ;) I took the MIPS-years estimation to break
RSA-1024, the estimation for breaking RSA-2048, and divided.
