I've been doing the thought exercises on what it would take to have forked
ant instances coupled to the extent that the child receives all properties
& definiitions, and can pump back messages for integration into the parents
logging channel. It'd be hard, but interesting -you could do tightly coupled
remote builds, forking <ant>, etc etc.
I dont have a solution other than maybe RMI -child app demand retrieves
config data from the parent, & sends log info back, maybe with pre-migrate
of the core stuff to speed up the fork across a network.
No plans to turn this into code in the foreseeable future, but I'd like the
underlying system to be midly amenable to the concept. I dont know where
this relates to ant startup options (as I'd obviously bypass Main) but the
new startup stuff may be involved.
