Hi,
Could you provide example captures of these protocols so we could take a look and se how difficult it would be to implement a dissector.

Unfortunately, packet-per.c does not support UNALIGNED PER now.

The asn2eth does not support ASN.1 classes. I.e. classes definitons has to be replaced 
with "pure" ASN.1 in the ASN.1 source.
