Export is indeed a facility not directly available with PyDia. I did some 
experiments regarding that with the 2nd bindings [1], [2] but that's 
slightly bitrotten since than. And it wont help with PyDia.

Not that obivous I think, but anyway you should be able to use the 
exisiting PyDia svg export (diasvg.py) directly from your PyDia plug-in.
Making use of Dia's meta info facility might also be an option, depending 
on the parser of your external program.
