Add export to Google spreadsheets.
From Google spreadsheets there is an API that can be used to export to various other flashcard programs.
Also, if numerous students were able to export to one teacher's spreadsheet, the teacher would get good data on the class's vocabulary profile.

Exporting to Google Sheets is easy, and takes seconds. The most foolproof way seems to be column by column. So for example select "Export" > "Original". This will send a TXT file to your downloads - Select All > Copy, and paste that into the first column, the rows will be automatically be filled. Then do the same thing with "Export" > "Translation" to the second row, and "Export" > "Context (with original word" to the third column, and Bob's your uncle. I then alphabetise it, and have a nice vocab list, to which it is easy to add notes, dictionary links, etc.
