Maybe we could subclass the SeqRecord for different types of
formats (sort of like the alignment class is for clustalw....).
Then a write method as you suggested would just print out the relevant 
format.  A set of converters could also be provided separately (again
just like for alignments).

It doesn't solve the preservation of information, but at least
it's a 'nice' design for the 'beefing up' of SeqRecord. Alternatively,
SeqFeature could be subclassed for that purpose if you want to
keep SeqRecord simpler.
