Jeremy, I've added some string types and I would like to see support
for some repeatedly used standard types like SEQUENCE OF or SET OF.
We could coordinate to enhance your ASN.1 module.

I'd also would like to have a separate BER/DER module for decoding
(maybe borrowed from pysnmp?). This would make it possible to also
import a BER/DER module in C if present (similar to common usage of
cPickle/pickle). The C module could be borrowed from e.g. OpenSSL or
BER from OpenLDAP.

Ciao, Michael.
