The word you use -- "dot", "point", "mark", "sub", -- is a matter of personal taste or else institutional style, but when in doubt a word which directly describes the symbol is usually fine (I would say point here).
Version numbers carry a similar ambiguity. Both the terms "dot release" and "point release" are valid, and version numbers can be read in a variety of ways. In the case of "Web 2.0," for example, both "dot" and "point" can be used:
There seem to be many possible ways of saying this - "two point oh", "two point zero", "two dot oh", two point nought", "two oh", "web two" - with a certain amount of variation according to nationality, company loyalties and other factors.
