I wrote nested varints. Gmail overrode me. The problem is that you can't DER encode an object in a single forward pass because you can't write the outermost object until its length is known and you don't know that till you have the lengths of the inner objects and so on.
BER is much easier because you can use the indefinite length encoding. DER would have been much easier if it had chosen the indefinite length encoding of lists and prohibited the definite length.
