It should be possible with some minor/medium effort (well I don't do the programing, else it would be major :), to make the dissector work with ATM as well. It's "only" a question of making the mapping to right AAL2 (instead of following the UDP frame, reading the Q.2630 and follow the AAL2).
/MartinPS. Wireshark today follow the FH very well even with encryption, it's to follow RLC-SDU that's problematic when ciphering is enabled. DS.
