[erlang-questions] asn1 and the new ssl module

Hi!

The new ssl implementation is pure Erlang as apposed to the old one 
where all ssl-stuff  is handled on c-level and then a clear-text 
message  is sent from c to Erlang via a socket
using the inet-driver to parse packet headers. Now in the new 
implementation the inet-drivers header parsing has to be emulated as the 
messages received on the socket
are encrypted and must be decrypted before header parsing can be done.
The first version of new ssl  released in R12B is not yet ready to 
replace the old one. For instance not all packet types are emulated.  
Only  {packet, N} and
{packet, cdr} is fully implemented and tested.  Before dropping the old 
ssl-solution of course all documented packet types will be supported. 
(Probably also the currently
undocumented http-packet type.)

ssl_connection.erl seems to not have any reference to that option.
