Although CLAM is already available, at the time of this writing its usage is still mainly internal to the MTG. It is still too early to evaluate its public acceptance. It is important to note that the framework will not be publicly advertised in a general sense until it reaches its 1.0 release.
Internally CLAM has been used in many different projects all of them already reviewed in section 3.2.3.
As for its external usage it may be mentioned that the CLAM mailing-list has now well above 100 subscribed members, of which about 25 are external to the MTG (note that we are considering students from the university also as internal users although they formally are not). The truth is that these members are not very active and, although we know they are using CLAM we do not have any news of what have been the final upcoming of their initial efforts.
