At first, I was thinking that this might not be a bad idea, however, on
second thought there might be memory issues.  Probably not huge memory
issues, but depending on the amount of data, it might be too costly in the
general use case.  I would guess that doing a StringIO approach would
probably be better than reworking savetxt.  Because savetxt already accepts
a file-like object, StringIO fits very nicely to the existing numpy
framework.

My 2 cents...
