Humm... IMHO, CAS is very flexible. You can use it to create so many 
different algorithms. For instance, CAS/DWCAS is used to create virtually 
every STM implementation I have seen. You can also do atomic pointers, proxy 
gc, ect...


As for HTM:

Transactional memory has overhead. Mutexs are probably more efficient.
