Well multiprocessor support always comes up....

As I may have mentioned in private, at PyCon 2008, in discussion with
folks off-line, an Erlang feature that interests folks that spoke with me, is hot-swapping. 

Closely related, another thing that I discussed was long-running transactions/compensation. Compensation is the ability to choose an alternative action for a transaction that cannot be atomic. In the WS-BPEL model, language wise, compensation involves taking snapshots of successful states, which are offered to the compensation handler when an error occurs. I haven't implemented compensation yet.
