Ah, right, the conflict is in the meaning of the TAB key.
There are two issues there:
1- the fact that there's no standard way to *extend* the meaning of
   TAB, so autocomplete and yasnippet may both *redefine* the key instead.
2- even if the two manage to redefine TAB "at the same time", the
   resulting behavior may prove too DWIMish.
