This should be quite easy, Seam Persistence already has code that checks various JNDI
locations for the TM.

would also need to expose TM as a bean. Weld could do this, but in general in Weld
we've tried to avoid exposing built in beans (especially for standard APIs) which
aren't spec defined as this could interfere with other people. So better to propose
this for CDI 1.1 IMO.
