Ancestry and familytreedna files

Hi,
would it be possible to provide similar functionality for raw data downloaded from familytreedna and ancestrydna websites?
ancestrydna file has the following structure (cols are separated by tabs like for 23andme but ancestry provides two alleles instead of one genotype):
#rsid chromosome position allele1 allele2
rs369202065 1 569388 G G
...
familytreedna .csv file looks like this (cols are separated by commas and put in double quotes):
#RSID,CHROMOSOME,POSITION,RESULT
"rs4477212","1","82154","AA"
...

Start by locating the existing 23andMe raw-data parser and its tests or usage entry points. Compare its expected input with the AncestryDNA tab-separated and FamilyTreeDNA quoted CSV examples, then verify that both formats produce the same kind of parsed SNP data; done means representative files from both services are accepted.
